Pull networking updates from David Miller: 1) Add VF IPSEC offload support in ixgbe, from Shannon Nelson. 2) Add zero-copy AF_XDP support to i40e, from Björn Töpel. 3) All in-tree drivers are converted to {g,s}et_link_ksettings() so we can get rid of the {g,s}et_settings ethtool callbacks, from Michal Kubecek. 4) Add software timestamping to veth driver, from Michael Walle. 5) More work to make packet classifiers and actions lockless, from Vlad Buslov. 6) Support sticky FDB entries in bridge, from Nikolay Aleksandrov. 7) Add ipv6 version of IP_MULTICAST_ALL sockopt, from Andre Naujoks. 8) Support batching of XDP buffers in vhost_net, from Jason Wang. 9) Add flow dissector BPF hook, from Petar Penkov. 10) i40e vf --> generic iavf conversion, from Jesse Brandeburg. 11) Add NLA_REJECT netlink attribute policy type, to signal when users provide attributes in situations which don't make sense. From Johannes Berg. 12) Switch TCP and fair-queue scheduler over to earliest departure time model. From Eric Dumazet. 13) Improve guest receive performance by doing rx busy polling in tx path of vhost networking driver, from Tonghao Zhang. 14) Add per-cgroup local storage to bpf 15) Add reference tracking to BPF, from Joe Stringer. The verifier can now make sure that references taken to objects are properly released by the program. 16) Support in-place encryption in TLS, from Vakul Garg. 17) Add new taprio packet scheduler, from Vinicius Costa Gomes. 18) Lots of selftests additions, too numerous to mention one by one here but all of which are very much appreciated. 19) Support offloading of eBPF programs containing BPF to BPF calls in nfp driver, frm Quentin Monnet. 20) Move dpaa2_ptp driver out of staging, from Yangbo Lu. 21) Lots of u32 classifier cleanups and simplifications, from Al Viro. 22) Add new strict versions of netlink message parsers, and enable them for some situations. From David Ahern. 23) Evict neighbour entries on carrier down, also from David Ahern. 24) Support BPF sk_msg verdict programs with kTLS, from Daniel Borkmann and John Fastabend. 25) Add support for filtering route dumps, from David Ahern. 26) New igc Intel driver for 2.5G parts, from Sasha Neftin et al. 27) Allow vxlan enslavement to bridges in mlxsw driver, from Ido Schimmel. 28) Add queue and stack map types to eBPF, from Mauricio Vasquez B. 29) Add back byte-queue-limit support to r8169, with all the bug fixes in other areas of the driver it works now! From Florian Westphal and Heiner Kallweit. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (2147 commits) tcp: add tcp_reset_xmit_timer() helper qed: Fix static checker warning Revert "be2net: remove desc field from be_eq_obj" Revert "net: simplify sock_poll_wait" net: socionext: Reset tx queue in ndo_stop net: socionext: Add dummy PHY register read in phy_write() net: socionext: Stop PHY before resetting netsec net: stmmac: Set OWN bit for jumbo frames arm64: dts: stratix10: Support Ethernet Jumbo frame tls: Add maintainers net: ethernet: ti: cpsw: unsync mcast entries while switch promisc mode octeontx2-af: Support for NIXLF's UCAST/PROMISC/ALLMULTI modes octeontx2-af: Support for setting MAC address octeontx2-af: Support for changing RSS algorithm octeontx2-af: NIX Rx flowkey configuration for RSS octeontx2-af: Install ucast and bcast pkt forwarding rules octeontx2-af: Add LMAC channel info to NIXLF_ALLOC response octeontx2-af: NPC MCAM and LDATA extract minimal configuration octeontx2-af: Enable packet length and csum validation octeontx2-af: Support for VTAG strip and capture ...

+Microsemi Ocelot SerDes muxing driver
+-------------------------------------
+
+On Microsemi Ocelot, there is a handful of registers in HSIO address
+space for setting up the SerDes to switch port muxing.
+
+A SerDes X can be "muxed" to work with switch port Y or Z for example.
+One specific SerDes can also be used as a PCIe interface.
+
+Hence, a SerDes represents an interface, be it an Ethernet or a PCIe one.
+
+There are two kinds of SerDes: SERDES1G supports 10/100Mbps in
+half/full-duplex and 1000Mbps in full-duplex mode while SERDES6G supports
+10/100Mbps in half/full-duplex and 1000/2500Mbps in full-duplex mode.
+
+Also, SERDES6G number (aka "macro") 0 is the only interface supporting
+QSGMII.
+
+This is a child of the HSIO syscon ("mscc,ocelot-hsio", see
+Documentation/devicetree/bindings/mips/mscc.txt) on the Microsemi Ocelot.
+
+Required properties:
+
+- compatible: should be "mscc,vsc7514-serdes"

+ The first number defines the input port to use for a given

+Notes on the DEC FDDIcontroller 700 (DEFZA-xx) driver v.1.1.4.
+
+
+DEC FDDIcontroller 700 is DEC's first-generation TURBOchannel FDDI
+network card, designed in 1990 specifically for the DECstation 5000
+model 200 workstation. The board is a single attachment station and
+it was manufactured in two variations, both of which are supported.
+
+First is the SAS MMF DEFZA-AA option, the original design implementing
+the standard MMF-PMD, however with a pair of ST connectors rather than
+the usual MIC connector. The other one is the SAS ThinWire/STP DEFZA-CA
+option, denoted 700-C, with the network medium selectable by a switch
+between the DEC proprietary ThinWire-PMD using a BNC connector and the
+standard STP-PMD using a DE-9F connector. This option can interface to
+a DECconcentrator 500 device and, in the case of the STP-PMD, also other
+FDDI equipment and was designed to make it easier to transition from
+existing IEEE 802.3 10BASE2 Ethernet and IEEE 802.5 Token Ring networks
+by providing means to reuse existing cabling.
+
+This driver handles any number of cards installed in a single system.
+They get fddi0, fddi1, etc. interface names assigned in the order of
+increasing TURBOchannel slot numbers.
+
+The board only supports DMA on the receive side. Transmission involves
+the use of PIO. As a result under a heavy transmission load there will
+be a significant impact on system performance.
+
+The board supports a 64-entry CAM for matching destination addresses.
+Two entries are preoccupied by the Directed Beacon and Ring Purger
+multicast addresses and the rest is used as a multicast filter. An
+all-multi mode is also supported for LLC frames and it is used if
+requested explicitly or if the CAM overflows. The promiscuous mode
+supports separate enables for LLC and SMT frames, but this driver
+doesn't support changing them individually.
+
+
+Known problems:
+
+None.
+
+
+To do:
+
+5. MAC address change. The card does not support changing the Media
+ Access Controller's address registers but a similar effect can be
+ achieved by adding an alias to the CAM. There is no way to disable
+ matching against the original address though.
+
+7. Queueing incoming/outgoing SMT frames in the driver if the SMT
+ receive/RMC transmit ring is full. (?)
+
+8. Retrieving/reporting FDDI/SNMP stats.
+
+
+Both success and failure reports are welcome.

+Identifying Your Adapter
+========================
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+https://www.intel.com/support
+
+
+Command Line Parameters
+=======================
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax::
+
+ modprobe e1000e [<option>=<VAL1>,<VAL2>,...]
+
+There needs to be a <VAL#> for each network port in the system supported by
+this driver. The values will be applied to each instance, in function order.
+For example::
+
+ modprobe e1000e InterruptThrottleRate=16000,16000
+
+In this case, there are two network ports supported by e1000e in the system.
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+NOTE: A descriptor describes a data buffer and attributes related to the data
+buffer. This information is accessed by the hardware.
+
+InterruptThrottleRate
+---------------------
+:Valid Range: 0,1,3,4,100-100000
+:Default Value: 3
+
+Interrupt Throttle Rate controls the number of interrupts each interrupt
+vector can generate per second. Increasing ITR lowers latency at the cost of
+increased CPU utilization, though it may help throughput in some circumstances.
+
+Setting InterruptThrottleRate to a value greater or equal to 100
+will program the adapter to send out a maximum of that many interrupts
+per second, even if more packets have come in. This reduces interrupt
+load on the system and can lower CPU utilization under heavy load,
+but will increase latency as packets are not processed as quickly.
+
+The default behaviour of the driver previously assumed a static
+InterruptThrottleRate value of 8000, providing a good fallback value for
+all traffic types, but lacking in small packet performance and latency.
+The hardware can handle many more small packets per second however, and
+for this reason an adaptive interrupt moderation algorithm was implemented.
+
+The driver has two adaptive modes (setting 1 or 3) in which
+it dynamically adjusts the InterruptThrottleRate value based on the traffic
+that it receives. After determining the type of incoming traffic in the last
+timeframe, it will adjust the InterruptThrottleRate to an appropriate value
+for that traffic.
+
+The algorithm classifies the incoming traffic every interval into
+classes. Once the class is determined, the InterruptThrottleRate value is
+adjusted to suit that traffic type the best. There are three classes defined:
+"Bulk traffic", for large amounts of packets of normal size; "Low latency",
+for small amounts of traffic and/or a significant percentage of small
+packets; and "Lowest latency", for almost completely small packets or
+minimal traffic.
+
+ - 0: Off
+ Turns off any interrupt moderation and may improve small packet latency.
+ However, this is generally not suitable for bulk throughput traffic due
+ to the increased CPU utilization of the higher interrupt rate.
+ - 1: Dynamic mode
+ This mode attempts to moderate interrupts per vector while maintaining
+ very low latency. This can sometimes cause extra CPU utilization. If
+ planning on deploying e1000e in a latency sensitive environment, this
+ parameter should be considered.
+ - 3: Dynamic Conservative mode (default)
+ In dynamic conservative mode, the InterruptThrottleRate value is set to
+ 4000 for traffic that falls in class "Bulk traffic". If traffic falls in
+ the "Low latency" or "Lowest latency" class, the InterruptThrottleRate is
+ increased stepwise to 20000. This default mode is suitable for most
+ applications.
+ - 4: Simplified Balancing mode
+ In simplified mode the interrupt rate is based on the ratio of TX and
+ RX traffic. If the bytes per second rate is approximately equal, the
+ interrupt rate will drop as low as 2000 interrupts per second. If the
+ traffic is mostly transmit or mostly receive, the interrupt rate could
+ be as high as 8000.
+ - 100-100000:
+ Setting InterruptThrottleRate to a value greater or equal to 100
+ will program the adapter to send at most that many interrupts per second,
+ even if more packets have come in. This reduces interrupt load on the
+ system and can lower CPU utilization under heavy load, but will increase
+ latency as packets are not processed as quickly.
+
+NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
+RxAbsIntDelay parameters. In other words, minimizing the receive and/or
+transmit absolute delays does not force the controller to generate more
+interrupts than what the Interrupt Throttle Rate allows.
+
+RxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 0
+
+This value delays the generation of receive interrupts in units of 1.024
+microseconds. Receive interrupt reduction can improve CPU efficiency if
+properly tuned for specific network traffic. Increasing this value adds extra
+latency to frame reception and can end up decreasing the throughput of TCP
+traffic. If the system is reporting dropped receives, this value may be set
+too high, causing the driver to run out of available receive descriptors.
+
+CAUTION: When setting RxIntDelay to a value other than 0, adapters may hang
+(stop transmitting) under certain network conditions. If this occurs a NETDEV
+WATCHDOG message is logged in the system event log. In addition, the
+controller is automatically reset, restoring the network connection. To
+eliminate the potential for the hang ensure that RxIntDelay is set to 0.
+
+RxAbsIntDelay
+-------------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 8
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+receive interrupt is generated. This value ensures that an interrupt is
+generated after the initial packet is received within the set amount of time,
+which is useful only if RxIntDelay is non-zero. Proper tuning, along with
+RxIntDelay, may improve traffic throughput in specific network conditions.
+
+TxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 8
+
+This value delays the generation of transmit interrupts in units of 1.024
+microseconds. Transmit interrupt reduction can improve CPU efficiency if
+properly tuned for specific network traffic. If the system is reporting
+dropped transmits, this value may be set too high causing the driver to run
+out of available transmit descriptors.
+
+TxAbsIntDelay
+-------------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 32
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+transmit interrupt is generated. It is useful only if TxIntDelay is non-zero.
+It ensures that an interrupt is generated after the initial Packet is sent on
+the wire within the set amount of time. Proper tuning, along with TxIntDelay,
+may improve traffic throughput in specific network conditions.
+
+copybreak
+---------
+:Valid Range: 0-xxxxxxx (0=off)
+:Default Value: 256
+
+The driver copies all packets below or equaling this size to a fresh receive
+buffer before handing it up the stack.
+This parameter differs from other parameters because it is a single (not 1,1,1
+etc.) parameter applied to all driver instances and it is also available
+during runtime at /sys/module/e1000e/parameters/copybreak.
+
+To use copybreak, type::
+
+ modprobe e1000e.ko copybreak=128
+
+SmartPowerDownEnable
+--------------------
+:Valid Range: 0,1
+:Default Value: 0 (disabled)
+
+Allows the PHY to turn off in lower power states. The user can turn off this
+parameter in supported chipsets.
+
+KumeranLockLoss
+---------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+This workaround skips resetting the PHY at shutdown for the initial silicon
+releases of ICH8 systems.
+
+IntMode
+-------
+:Valid Range: 0-2
+:Default Value: 0
+
+ +-------+----------------+
+ | Value | Interrupt Mode |
+ +=======+================+
+ | 0 | Legacy |
+ +-------+----------------+
+ | 1 | MSI |
+ +-------+----------------+
+ | 2 | MSI-X |
+ +-------+----------------+
+
+IntMode allows load time control over the type of interrupt registered for by
+the driver. MSI-X is required for multiple queue support, and some kernels and
+combinations of kernel .config options will force a lower level of interrupt
+support.
+
+This command will show different values for each type of interrupt::
+
+ cat /proc/interrupts
+
+CrcStripping
+------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+Strip the CRC from received packets before sending up the network stack. If
+you have a machine with a BMC enabled but cannot receive IPMI traffic after
+loading or enabling the driver, try disabling this feature.
+
+WriteProtectNVM
+---------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+If set to 1, configure the hardware to ignore all write/erase cycles to the
+GbE region in the ICHx NVM (in order to prevent accidental corruption of the
+NVM). This feature can be disabled by setting the parameter to 0 during initial
+driver load.
+
+NOTE: The machine must be power cycled (full off/on) when enabling NVM writes
+via setting the parameter to zero. Once the NVM has been locked (via the
+parameter at 1 when the driver loads) it cannot be unlocked except via power
+cycle.
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level of debug messages displayed in the system logs.
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+ ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+ ip link set mtu 9000 dev eth<x>
+ ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 8996. This value coincides
+with the maximum Jumbo Frames size of 9018 bytes.
+
+NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
+poor performance or loss of link.
+
+NOTE: The following adapters limit Jumbo Frames sized packets to a maximum of
+4088 bytes:
+
+ - Intel(R) 82578DM Gigabit Network Connection
+ - Intel(R) 82577LM Gigabit Network Connection
+
+The following adapters do not support Jumbo Frames:
+
+ - Intel(R) PRO/1000 Gigabit Server Adapter
+ - Intel(R) PRO/1000 PM Network Connection
+ - Intel(R) 82562G 10/100 Network Connection
+ - Intel(R) 82562G-2 10/100 Network Connection
+ - Intel(R) 82562GT 10/100 Network Connection
+ - Intel(R) 82562GT-2 10/100 Network Connection
+ - Intel(R) 82562V 10/100 Network Connection
+ - Intel(R) 82562V-2 10/100 Network Connection
+ - Intel(R) 82566DC Gigabit Network Connection
+ - Intel(R) 82566DC-2 Gigabit Network Connection
+ - Intel(R) 82566DM Gigabit Network Connection
+ - Intel(R) 82566MC Gigabit Network Connection
+ - Intel(R) 82566MM Gigabit Network Connection
+ - Intel(R) 82567V-3 Gigabit Network Connection
+ - Intel(R) 82577LC Gigabit Network Connection
+ - Intel(R) 82578DC Gigabit Network Connection
+
+NOTE: Jumbo Frames cannot be configured on an 82579-based Network device if
+MACSec is enabled on the system.
+
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+
+https://www.kernel.org/pub/software/network/ethtool/
+
+NOTE: When validating enable/disable tests on some parts (for example, 82578),
+it is necessary to add a few seconds between tests when working with ethtool.
+
+
+Speed and Duplex Configuration
+------------------------------
+In addressing speed and duplex configuration issues, you need to distinguish
+between copper-based adapters and fiber-based adapters.
+
+In the default mode, an Intel(R) Ethernet Network Adapter using copper
+connections will attempt to auto-negotiate with its link partner to determine
+the best setting. If the adapter cannot establish link with the link partner
+using auto-negotiation, you may need to manually configure the adapter and link
+partner to identical settings to establish link and pass packets. This should
+only be needed when attempting to link with an older switch that does not
+support auto-negotiation or one that has been forced to a specific speed or
+duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
+and higher cannot be forced. Use the autonegotiation advertising setting to
+manually set devices for 1 Gbps and higher.
+
+Speed, duplex, and autonegotiation advertising are configured through the
+ethtool* utility.
+
+Caution: Only experienced network administrators should force speed and duplex
+or change autonegotiation advertising manually. The settings at the switch must
+always match the adapter settings. Adapter performance may suffer or your
+adapter may not operate if you configure the adapter differently from your
+switch.
+
+An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
+will not attempt to auto-negotiate with its link partner since those adapters
+operate only in full duplex and only at their native speed.
+
+
+Enabling Wake on LAN* (WoL)
+---------------------------
+WoL is configured through the ethtool* utility.
+
+WoL will be enabled on the system during the next shut down or reboot. For
+this driver version, in order to enable WoL, the e1000e driver must be loaded
+prior to shutting down or suspending the system.
+
+NOTE: Wake on LAN is only supported on port A for the following devices:
+- Intel(R) PRO/1000 PT Dual Port Network Connection
+- Intel(R) PRO/1000 PT Dual Port Server Connection
+- Intel(R) PRO/1000 PT Dual Port Server Adapter
+- Intel(R) PRO/1000 PF Dual Port Server Adapter
+- Intel(R) PRO/1000 PT Quad Port Server Adapter
+- Intel(R) Gigabit PT Quad Port Server ExpressModule

-Command Line Parameters
-=======================
-
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-NOTES: For more information about the InterruptThrottleRate,
- RxIntDelay, TxIntDelay, RxAbsIntDelay, and TxAbsIntDelay
- parameters, see the application note at:
- http://www.intel.com/design/network/applnots/ap450.htm
-
-InterruptThrottleRate
----------------------
-Valid Range: 0,1,3,4,100-100000 (0=off, 1=dynamic, 3=dynamic conservative,
- 4=simplified balancing)
-Default Value: 3
-
-The driver can limit the amount of interrupts per second that the adapter
-will generate for incoming packets. It does this by writing a value to the
-adapter that is based on the maximum amount of interrupts that the adapter
-will generate per second.
-
-Setting InterruptThrottleRate to a value greater or equal to 100
-will program the adapter to send out a maximum of that many interrupts
-per second, even if more packets have come in. This reduces interrupt
-load on the system and can lower CPU utilization under heavy load,
-but will increase latency as packets are not processed as quickly.
-
-The default behaviour of the driver previously assumed a static
-InterruptThrottleRate value of 8000, providing a good fallback value for
-all traffic types, but lacking in small packet performance and latency.
-The hardware can handle many more small packets per second however, and
-for this reason an adaptive interrupt moderation algorithm was implemented.
-
-The driver has two adaptive modes (setting 1 or 3) in which
-it dynamically adjusts the InterruptThrottleRate value based on the traffic
-that it receives. After determining the type of incoming traffic in the last
-timeframe, it will adjust the InterruptThrottleRate to an appropriate value
-for that traffic.
-
-The algorithm classifies the incoming traffic every interval into
-classes. Once the class is determined, the InterruptThrottleRate value is
-adjusted to suit that traffic type the best. There are three classes defined:
-"Bulk traffic", for large amounts of packets of normal size; "Low latency",
-for small amounts of traffic and/or a significant percentage of small
-packets; and "Lowest latency", for almost completely small packets or
-minimal traffic.
-
-In dynamic conservative mode, the InterruptThrottleRate value is set to 4000
-for traffic that falls in class "Bulk traffic". If traffic falls in the "Low
-latency" or "Lowest latency" class, the InterruptThrottleRate is increased
-stepwise to 20000. This default mode is suitable for most applications.
-
-For situations where low latency is vital such as cluster or
-grid computing, the algorithm can reduce latency even more when
-InterruptThrottleRate is set to mode 1. In this mode, which operates
-the same as mode 3, the InterruptThrottleRate will be increased stepwise to
-70000 for traffic in class "Lowest latency".
-
-In simplified mode the interrupt rate is based on the ratio of TX and
-RX traffic. If the bytes per second rate is approximately equal, the
-interrupt rate will drop as low as 2000 interrupts per second. If the
-traffic is mostly transmit or mostly receive, the interrupt rate could
-be as high as 8000.
-
-Setting InterruptThrottleRate to 0 turns off any interrupt moderation
-and may improve small packet latency, but is generally not suitable
-for bulk throughput traffic.
-
-NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
- RxAbsIntDelay parameters. In other words, minimizing the receive
- and/or transmit absolute delays does not force the controller to
- generate more interrupts than what the Interrupt Throttle Rate
- allows.
-
-NOTE: When e1000e is loaded with default settings and multiple adapters
- are in use simultaneously, the CPU utilization may increase non-
- linearly. In order to limit the CPU utilization without impacting
- the overall throughput, we recommend that you load the driver as
- follows:
-
- modprobe e1000e InterruptThrottleRate=3000,3000,3000
-
- This sets the InterruptThrottleRate to 3000 interrupts/sec for
- the first, second, and third instances of the driver. The range
- of 2000 to 3000 interrupts per second works on a majority of
- systems and is a good starting point, but the optimal value will
- be platform-specific. If CPU utilization is not a concern, use
- RX_POLLING (NAPI) and default driver settings.
-
-RxIntDelay
-----------
-Valid Range: 0-65535 (0=off)
-Default Value: 0
-
-This value delays the generation of receive interrupts in units of 1.024
-microseconds. Receive interrupt reduction can improve CPU efficiency if
-properly tuned for specific network traffic. Increasing this value adds
-extra latency to frame reception and can end up decreasing the throughput
-of TCP traffic. If the system is reporting dropped receives, this value
-may be set too high, causing the driver to run out of available receive
-descriptors.
-
-CAUTION: When setting RxIntDelay to a value other than 0, adapters may
- hang (stop transmitting) under certain network conditions. If
- this occurs a NETDEV WATCHDOG message is logged in the system
- event log. In addition, the controller is automatically reset,
- restoring the network connection. To eliminate the potential
- for the hang ensure that RxIntDelay is set to 0.
-
-RxAbsIntDelay
--------------
-Valid Range: 0-65535 (0=off)
-Default Value: 8
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-receive interrupt is generated. Useful only if RxIntDelay is non-zero,
-this value ensures that an interrupt is generated after the initial
-packet is received within the set amount of time. Proper tuning,
-along with RxIntDelay, may improve traffic throughput in specific network
-conditions.
-
-TxIntDelay
-----------
-Valid Range: 0-65535 (0=off)
-Default Value: 8
-
-This value delays the generation of transmit interrupts in units of
-1.024 microseconds. Transmit interrupt reduction can improve CPU
-efficiency if properly tuned for specific network traffic. If the
-system is reporting dropped transmits, this value may be set too high
-causing the driver to run out of available transmit descriptors.
-
-TxAbsIntDelay
--------------
-Valid Range: 0-65535 (0=off)
-Default Value: 32
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-transmit interrupt is generated. Useful only if TxIntDelay is non-zero,
-this value ensures that an interrupt is generated after the initial
-packet is sent on the wire within the set amount of time. Proper tuning,
-along with TxIntDelay, may improve traffic throughput in specific
-network conditions.
-
-Copybreak
----------
-Valid Range: 0-xxxxxxx (0=off)
-Default Value: 256
-
-Driver copies all packets below or equaling this size to a fresh RX
-buffer before handing it up the stack.
-
-This parameter is different than other parameters, in that it is a
-single (not 1,1,1 etc.) parameter applied to all driver instances and
-it is also available during runtime at
-/sys/module/e1000e/parameters/copybreak
-
-SmartPowerDownEnable
---------------------
-Valid Range: 0-1
-Default Value: 0 (disabled)
-
-Allows PHY to turn off in lower power states. The user can set this parameter
-in supported chipsets.
-
-KumeranLockLoss
----------------
-Valid Range: 0-1
-Default Value: 1 (enabled)
-
-This workaround skips resetting the PHY at shutdown for the initial
-silicon releases of ICH8 systems.
-
-IntMode
--------
-Valid Range: 0-2 (0=legacy, 1=MSI, 2=MSI-X)
-Default Value: 2
-
-Allows changing the interrupt mode at module load time, without requiring a
-recompile. If the driver load fails to enable a specific interrupt mode, the
-driver will try other interrupt modes, from least to most compatible. The
-interrupt order is MSI-X, MSI, Legacy. If specifying MSI (IntMode=1)
-interrupts, only MSI and Legacy will be attempted.
-
-CrcStripping
-------------
-Valid Range: 0-1
-Default Value: 1 (enabled)
-
-Strip the CRC from received packets before sending up the network stack. If
-you have a machine with a BMC enabled but cannot receive IPMI traffic after
-loading or enabling the driver, try disabling this feature.
-
-WriteProtectNVM
----------------
-Valid Range: 0,1
-Default Value: 1
-
-If set to 1, configure the hardware to ignore all write/erase cycles to the
-GbE region in the ICHx NVM (in order to prevent accidental corruption of the
-NVM). This feature can be disabled by setting the parameter to 0 during initial
-driver load.
-NOTE: The machine must be power cycled (full off/on) when enabling NVM writes
-via setting the parameter to zero. Once the NVM has been locked (via the
-parameter at 1 when the driver loads) it cannot be unlocked except via power
-cycle.
-
-Additional Configurations
-=========================
-
- Jumbo Frames
- ------------
- Jumbo Frames support is enabled by changing the MTU to a value larger than
- the default of 1500. Use the ifconfig command to increase the MTU size.
- For example:
-
- ifconfig eth<x> mtu 9000 up
-
- This setting is not saved across reboots.
-
- Notes:
-
- - The maximum MTU setting for Jumbo Frames is 9216. This value coincides
- with the maximum Jumbo Frames size of 9234 bytes.
-
- - Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
- poor performance or loss of link.
-
- - Some adapters limit Jumbo Frames sized packets to a maximum of
- 4096 bytes and some adapters do not support Jumbo Frames.
-
- - Jumbo Frames cannot be configured on an 82579-based Network device, if
- MACSec is enabled on the system.
-
- ethtool
- -------
- The driver utilizes the ethtool interface for driver configuration and
- diagnostics, as well as displaying statistical information. We
- strongly recommend downloading the latest version of ethtool at:
-
- https://kernel.org/pub/software/network/ethtool/
-
- NOTE: When validating enable/disable tests on some parts (82578, for example)
- you need to add a few seconds between tests when working with ethtool.
-
- Speed and Duplex
- ----------------
- Speed and Duplex are configured through the ethtool* utility. For
- instructions, refer to the ethtool man page.
-
- Enabling Wake on LAN* (WoL)
- ---------------------------
- WoL is configured through the ethtool* utility. For instructions on
- enabling WoL with ethtool, refer to the ethtool man page.
-
- WoL will be enabled on the system during the next shut down or reboot.
- For this driver version, in order to enable WoL, the e1000e driver must be
- loaded when shutting down or rebooting the system.
-
- In most cases Wake On LAN is only supported on port A for multiple port
- adapters. To verify if a port supports Wake on Lan run ethtool eth<X>.

+Identifying Your Adapter
+========================
+The driver in this release is compatible with devices based on the Intel(R)
+Ethernet Multi-host Controller.
+
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+
+Flow Control
+------------
+The Intel(R) Ethernet Switch Host Interface Driver does not support Flow
+Control. It will not send pause frames. This may result in dropped frames.
+
+
+Virtual Functions (VFs)
+-----------------------
+Use sysfs to enable VFs.
+Valid Range: 0-64
+
+For example::
+
+ echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs //enable VFs
+ echo 0 > /sys/class/net/$dev/device/sriov_numvfs //disable VFs
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When SR-IOV mode is enabled, hardware VLAN filtering and VLAN tag
+stripping/insertion will remain enabled. Please remove the old VLAN filter
+before the new VLAN filter is added. For example::
+
+ ip link set eth0 vf 0 vlan 100 // set vlan 100 for VF 0
+ ip link set eth0 vf 0 vlan 0 // Delete vlan 100
+ ip link set eth0 vf 0 vlan 200 // set a new vlan 200 for VF 0
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+ ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+ ip link set mtu 9000 dev eth<x>
+ ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 15342. This value coincides
+with the maximum Jumbo Frames size of 15364 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+
+Generic Receive Offload, aka GRO
+--------------------------------
+The driver supports the in-kernel software implementation of GRO. GRO has
+shown that by coalescing Rx traffic into larger chunks of data, CPU
+utilization can be significantly reduced when under large Rx load. GRO is an
+evolution of the previously-used LRO interface. GRO is able to coalesce
+other protocols besides TCP. It's also safe to use with configurations that
+are problematic for LRO, namely bridging and iSCSI.
+
+
+
+Supported ethtool Commands and Options for Filtering
+----------------------------------------------------
+-n --show-nfc
+ Retrieves the receive network flow classification configurations.
+
+rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6
+ Retrieves the hash options for the specified network traffic type.
+
+-N --config-nfc
+ Configures the receive network flow classification.
+
+rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 m|v|t|s|d|f|n|r
+ Configures the hash options for the specified network traffic type.
+
+- udp4: UDP over IPv4
+- udp6: UDP over IPv6
+- f Hash on bytes 0 and 1 of the Layer 4 header of the rx packet.
+- n Hash on bytes 2 and 3 of the Layer 4 header of the rx packet.

+ #echo 0 > /sys/class/net/$dev/device/sriov_numvfs #disable VFs
+
+For example, the following instructions will configure PF eth0 and the first VF
+on VLAN 10::
+
+ $ ip link set dev eth0 vf 0 vlan 10
+
+VLAN Tag Packet Steering
+------------------------
+Allows you to send all packets with a specific VLAN tag to a particular SR-IOV
+virtual function (VF). Further, this feature allows you to designate a
+particular VF as trusted, and allows that trusted VF to request selective
+promiscuous mode on the Physical Function (PF).
+
+To set a VF as trusted or untrusted, enter the following command in the
+Hypervisor::
+
+ # ip link set dev eth0 vf 1 trust [on|off]
+
+Once the VF is designated as trusted, use the following commands in the VM to
+set the VF to promiscuous mode.
+
+::
+
+ For promiscuous all:
+ #ip link set eth2 promisc on
+ Where eth2 is a VF interface in the VM
+
+ For promiscuous Multicast:
+ #ip link set eth2 allmulticast on
+ Where eth2 is a VF interface in the VM
+
+NOTE: By default, the ethtool priv-flag vf-true-promisc-support is set to
+"off",meaning that promiscuous mode for the VF will be limited. To set the
+promiscuous mode for the VF to true promiscuous and allow the VF to see all
+ingress traffic, use the following command::
+
+ #ethtool -set-priv-flags p261p1 vf-true-promisc-support on
+
+The vf-true-promisc-support priv-flag does not enable promiscuous mode; rather,
+it designates which type of promiscuous mode (limited or true) you will get
+when you enable promiscuous mode using the ip link commands above. Note that
+this is a global setting that affects the entire device. However,the
+vf-true-promisc-support priv-flag is only exposed to the first PF of the
+device. The PF remains in limited promiscuous mode (unless it is in MFP mode)
+regardless of the vf-true-promisc-support setting.
+
+Now add a VLAN interface on the VF interface::
+
+ #ip link add link eth2 name eth2.100 type vlan id 100
+
+Note that the order in which you set the VF to promiscuous mode and add the
+VLAN interface does not matter (you can do either first). The end result in
+this example is that the VF will get all traffic that is tagged with VLAN 100.
+
+Intel(R) Ethernet Flow Director
+-------------------------------
+The Intel Ethernet Flow Director performs the following tasks:
+
+- Directs receive packets according to their flows to different queues.
+- Enables tight control on routing a flow in the platform.
+- Matches flows and CPU cores for flow affinity.
+- Supports multiple parameters for flexible flow classification and load
+ balancing (in SFP mode only).
+
+NOTE: The Linux i40e driver supports the following flow types: IPv4, TCPv4, and
+UDPv4. For a given flow type, it supports valid combinations of IP addresses
+(source or destination) and UDP/TCP ports (source and destination). For
+example, you can supply only a source IP address, a source IP address and a
+destination port, or any combination of one or more of these four parameters.
+
+NOTE: The Linux i40e driver allows you to filter traffic based on a
+user-defined flexible two-byte pattern and offset by using the ethtool user-def
+and mask fields. Only L3 and L4 flow types are supported for user-defined
+flexible filters. For a given flow type, you must clear all Intel Ethernet Flow
+Director filters before changing the input set (for that flow type).
+
+To enable or disable the Intel Ethernet Flow Director::
+
+ # ethtool -K ethX ntuple <on|off>
+
+When disabling ntuple filters, all the user programmed filters are flushed from
+the driver cache and hardware. All needed filters must be re-added when ntuple
+is re-enabled.
+
+To add a filter that directs packet to queue 2, use -U or -N switch::
+
+ # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+ 192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
+
+To set a filter using only the source and destination IP address::
+
+ # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+ 192.168.10.2 action 2 [loc 1]
+
+To see the list of filters currently present::
+
+ # ethtool <-u|-n> ethX
+
+Application Targeted Routing (ATR) Perfect Filters
+--------------------------------------------------
+ATR is enabled by default when the kernel is in multiple transmit queue mode.
+An ATR Intel Ethernet Flow Director filter rule is added when a TCP-IP flow
+starts and is deleted when the flow ends. When a TCP-IP Intel Ethernet Flow
+Director rule is added from ethtool (Sideband filter), ATR is turned off by the
+driver. To re-enable ATR, the sideband can be disabled with the ethtool -K
+option. For example::
+
+ ethtool –K [adapter] ntuple [off|on]
+
+If sideband is re-enabled after ATR is re-enabled, ATR remains enabled until a
+TCP-IP flow is added. When all TCP-IP sideband rules are deleted, ATR is
+automatically re-enabled.
+
+Packets that match the ATR rules are counted in fdir_atr_match stats in
+ethtool, which also can be used to verify whether ATR rules still exist.
+
+Sideband Perfect Filters
+------------------------
+Sideband Perfect Filters are used to direct traffic that matches specified
+characteristics. They are enabled through ethtool's ntuple interface. To add a
+new filter use the following command::
+
+ ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
+ dst-port <port> action <queue>
+
+Where:
+ <device> - the ethernet device to program
+ <type> - can be ip4, tcp4, udp4, or sctp4
+ <ip> - the ip address to match on
+ <port> - the port number to match on
+ <queue> - the queue to direct traffic towards (-1 discards matching traffic)
+
+Use the following command to display all of the active filters::
+
+ ethtool -u <device>
+
+Use the following command to delete a filter::
+
+ ethtool -U <device> delete <N>
+
+Where <N> is the filter id displayed when printing all the active filters, and
+may also have been specified using "loc <N>" when adding the filter.
+
+The following example matches TCP traffic sent from 192.168.0.1, port 5300,
+directed to 192.168.0.5, port 80, and sends it to queue 7::
+
+ ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
+ src-port 5300 dst-port 80 action 7
+
+For each flow-type, the programmed filters must all have the same matching
+input set. For example, issuing the following two commands is acceptable::
+
+ ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+ ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
+
+Issuing the next two commands, however, is not acceptable, since the first
+specifies src-ip and the second specifies dst-ip::
+
+ ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+ ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
+
+The second command will fail with an error. You may program multiple filters
+with the same fields, using different values, but, on one device, you may not
+program two tcp4 filters with different matching fields.
+
+Matching on a sub-portion of a field is not supported by the i40e driver, thus
+partial mask fields are not supported.
+
+The driver also supports matching user-defined data within the packet payload.
+This flexible data is specified using the "user-def" field of the ethtool
+command in the following way:
+
++----------------------------+--------------------------+
+| 31 28 24 20 16 | 15 12 8 4 0 |
++----------------------------+--------------------------+
+| offset into packet payload | 2 bytes of flexible data |
++----------------------------+--------------------------+
+
+For example,
+
+::
+
+ ... user-def 0x4FFFF ...
+
+tells the filter to look 4 bytes into the payload and match that value against
+0xFFFF. The offset is based on the beginning of the payload, and not the
+beginning of the packet. Thus
+
+::
+
+ flow-type tcp4 ... user-def 0x8BEAF ...
+
+would match TCP/IPv4 packets which have the value 0xBEAF 8 bytes into the
+TCP/IPv4 payload.
+
+Note that ICMP headers are parsed as 4 bytes of header and 4 bytes of payload.
+Thus to match the first byte of the payload, you must actually add 4 bytes to
+the offset. Also note that ip4 filters match both ICMP frames as well as raw
+(unknown) ip4 frames, where the payload will be the L3 payload of the IP4 frame.
+
+The maximum offset is 64. The hardware will only read up to 64 bytes of data
+from the payload. The offset must be even because the flexible data is 2 bytes
+long and must be aligned to byte 0 of the packet payload.
+
+The user-defined flexible offset is also considered part of the input set and
+cannot be programmed separately for multiple filters of the same type. However,
+the flexible data is not part of the input set and multiple filters may use the
+same offset but match against different data.
+
+To create filters that direct traffic to a specific Virtual Function, use the
+"action" parameter. Specify the action as a 64 bit value, where the lower 32
+bits represents the queue number, while the next 8 bits represent which VF.
+Note that 0 is the PF, so the VF identifier is offset by 1. For example::
+
+ ... action 0x800000002 ...
+
+specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
+that VF.
+
+Note that these filters will not break internal routing rules, and will not
+route traffic that otherwise would not have been sent to the specified Virtual
+Function.
+
+Setting the link-down-on-close Private Flag
+-------------------------------------------
+When the link-down-on-close private flag is set to "on", the port's link will
+go down when the interface is brought down using the ifconfig ethX down command.
+
+Use ethtool to view and set link-down-on-close, as follows::
+
+ ethtool --show-priv-flags ethX
+ ethtool --set-priv-flags ethX link-down-on-close [on|off]
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+ dmesg -n 8
+
+NOTE: This setting is not saved across reboots.
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+ ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+ ip link set mtu 9000 dev eth<x>
+ ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file::
+
+ /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
+ /etc/sysconfig/network/<config_file> // for SLES
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9702. This value coincides
+with the maximum Jumbo Frames size of 9728 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+Supported ethtool Commands and Options for Filtering
+----------------------------------------------------
+-n --show-nfc
+ Retrieves the receive network flow classification configurations.
+
+rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6
+ Retrieves the hash options for the specified network traffic type.
+
+-N --config-nfc
+ Configures the receive network flow classification.
+
+rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 m|v|t|s|d|f|n|r...
+ Configures the hash options for the specified network traffic type.
+
+udp4 UDP over IPv4
+udp6 UDP over IPv6
+
+f Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
+n Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
+
+Speed and Duplex Configuration
+------------------------------
+In addressing speed and duplex configuration issues, you need to distinguish
+between copper-based adapters and fiber-based adapters.
+
+In the default mode, an Intel(R) Ethernet Network Adapter using copper
+connections will attempt to auto-negotiate with its link partner to determine
+the best setting. If the adapter cannot establish link with the link partner
+using auto-negotiation, you may need to manually configure the adapter and link
+partner to identical settings to establish link and pass packets. This should
+only be needed when attempting to link with an older switch that does not
+support auto-negotiation or one that has been forced to a specific speed or
+duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
+and higher cannot be forced. Use the autonegotiation advertising setting to
+manually set devices for 1 Gbps and higher.
+
+NOTE: You cannot set the speed for devices based on the Intel(R) Ethernet
+Network Adapter XXV710 based devices.
+
+Speed, duplex, and autonegotiation advertising are configured through the
+ethtool* utility.
+
+Caution: Only experienced network administrators should force speed and duplex
+or change autonegotiation advertising manually. The settings at the switch must
+always match the adapter settings. Adapter performance may suffer or your
+adapter may not operate if you configure the adapter differently from your
+switch.
+
+An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
+will not attempt to auto-negotiate with its link partner since those adapters
+operate only in full duplex and only at their native speed.
+
+NAPI
+----
+NAPI (Rx polling mode) is supported in the i40e driver.
+For more information on NAPI, see
+https://wiki.linuxfoundation.org/networking/napi
+
+Flow Control
+------------
+Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
+receiving and transmitting pause frames for i40e. When transmit is enabled,
+pause frames are generated when the receive packet buffer crosses a predefined
+threshold. When receive is enabled, the transmit unit will halt for the time
+delay specified when a pause frame is received.
+
+NOTE: You must have a flow control capable link partner.
+
+Flow Control is on by default.
+
+Use ethtool to change the flow control settings.
+
+To enable or disable Rx or Tx Flow Control::
+
+ ethtool -A eth? rx <on|off> tx <on|off>
+
+Note: This command only enables or disables Flow Control if auto-negotiation is
+disabled. If auto-negotiation is enabled, this command changes the parameters
+used for auto-negotiation with the link partner.
+
+To enable or disable auto-negotiation::
+
+ ethtool -s eth? autoneg <on|off>
+
+Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
+on your device, you may not be able to change the auto-negotiation setting.
+
+RSS Hash Flow
+-------------
+Allows you to set the hash bytes per flow type and any combination of one or
+more options for Receive Side Scaling (RSS) hash byte configuration.
+
+::
+
+ # ethtool -N <dev> rx-flow-hash <type> <option>
+
+Where <type> is:
+ tcp4 signifying TCP over IPv4
+ udp4 signifying UDP over IPv4
+ tcp6 signifying TCP over IPv6
+ udp6 signifying UDP over IPv6
+And <option> is one or more of:
+ s Hash on the IP source address of the Rx packet.
+ d Hash on the IP destination address of the Rx packet.
+ f Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
+ n Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+NOTE: This feature can be disabled for a specific Virtual Function (VF)::
+
+ ip link set <pf dev> vf <vf id> spoofchk {off|on}
+
+IEEE 1588 Precision Time Protocol (PTP) Hardware Clock (PHC)
+------------------------------------------------------------
+Precision Time Protocol (PTP) is used to synchronize clocks in a computer
+network. PTP support varies among Intel devices that support this driver. Use
+"ethtool -T <netdev name>" to get a definitive list of PTP capabilities
+supported by the device.
+
+IEEE 802.1ad (QinQ) Support
+---------------------------
+The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
+IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
+"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
+allow L2 tunneling and the ability to segregate traffic within a particular
+VLAN ID, among other uses.
+
+The following are examples of how to configure 802.1ad (QinQ)::
+
+ ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
+ ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
+
+Where "24" and "371" are example VLAN IDs.
+
+NOTES:
+ Receive checksum offloads, cloud filters, and VLAN acceleration are not
+ supported for 802.1ad (QinQ) packets.
+
+VXLAN and GENEVE Overlay HW Offloading
+--------------------------------------
+Virtual Extensible LAN (VXLAN) allows you to extend an L2 network over an L3
+network, which may be useful in a virtualized or cloud environment. Some
+Intel(R) Ethernet Network devices perform VXLAN processing, offloading it from
+the operating system. This reduces CPU utilization.
+
+VXLAN offloading is controlled by the Tx and Rx checksum offload options
+provided by ethtool. That is, if Tx checksum offload is enabled, and the
+adapter has the capability, VXLAN offloading is also enabled.
+
+Support for VXLAN and GENEVE HW offloading is dependent on kernel support of
+the HW offloading features.
+
+Multiple Functions per Port
+---------------------------
+Some adapters based on the Intel Ethernet Controller X710/XL710 support
+multiple functions on a single physical port. Configure these functions through
+the System Setup/BIOS.
+
+Minimum TX Bandwidth is the guaranteed minimum data transmission bandwidth, as
+a percentage of the full physical port link speed, that the partition will
+receive. The bandwidth the partition is awarded will never fall below the level
+you specify.
+
+The range for the minimum bandwidth values is:
+1 to ((100 minus # of partitions on the physical port) plus 1)
+For example, if a physical port has 4 partitions, the range would be:
+1 to ((100 - 4) + 1 = 97)
+
+The Maximum Bandwidth percentage represents the maximum transmit bandwidth
+allocated to the partition as a percentage of the full physical port link
+speed. The accepted range of values is 1-100. The value is used as a limiter,
+should you chose that any one particular function not be able to consume 100%
+of a port's bandwidth (should it be available). The sum of all the values for
+Maximum Bandwidth is not restricted, because no more than 100% of a port's
+bandwidth can ever be used.
+
+NOTE: X710/XXV710 devices fail to enable Max VFs (64) when Multiple Functions
+per Port (MFP) and SR-IOV are enabled. An error from i40e is logged that says
+"add vsi failed for VF N, aq_err 16". To workaround the issue, enable less than
+64 virtual functions (VFs).
+
+Data Center Bridging (DCB)
+--------------------------
+DCB is a configuration Quality of Service implementation in hardware. It uses
+the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
+different priorities that traffic can be filtered into. It also enables
+priority flow control (802.1Qbb) which can limit or eliminate the number of
+dropped packets during network stress. Bandwidth can be allocated to each of
+these priorities, which is enforced at the hardware level (802.1Qaz).
+
+Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
+802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
+and can accept settings from a DCBX capable peer. Software configuration of
+DCBX parameters via dcbtool/lldptool are not supported.
+
+NOTE: Firmware LLDP can be disabled by setting the private flag disable-fw-lldp.
+
+The i40e driver implements the DCB netlink interface layer to allow user-space
+to communicate with the driver and query DCB configuration for the port.
+
+NOTE:
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.
+
+Interrupt Rate Limiting
+-----------------------
+:Valid Range: 0-235 (0=no limit)
+
+The Intel(R) Ethernet Controller XL710 family supports an interrupt rate
+limiting mechanism. The user can control, via ethtool, the number of
+microseconds between interrupts.
+
+Syntax::
+
+ # ethtool -C ethX rx-usecs-high N
+
+The range of 0-235 microseconds provides an effective range of 4,310 to 250,000
+interrupts per second. The value of rx-usecs-high can be set independently of
+rx-usecs and tx-usecs in the same ethtool command, and is also independent of
+the adaptive interrupt moderation algorithm. The underlying hardware supports
+granularity in 4-microsecond intervals, so adjacent values may result in the
+same interrupt rate.
+
+One possible use case is the following::
+
+ # ethtool -C ethX adaptive-rx off adaptive-tx off rx-usecs-high 20 rx-usecs \
+ 5 tx-usecs 5
+
+The above command would disable adaptive interrupt moderation, and allow a
+maximum of 5 microseconds before indicating a receive or transmit was complete.
+However, instead of resulting in as many as 200,000 interrupts per second, it
+limits total interrupts per second to 50,000 via the rx-usecs-high parameter.
+
+Performance Optimization
+========================
+Driver defaults are meant to fit a wide variety of workloads, but if further
+optimization is required we recommend experimenting with the following settings.
+
+NOTE: For better performance when processing small (64B) frame sizes, try
+enabling Hyper threading in the BIOS in order to increase the number of logical
+cores in the system and subsequently increase the number of queues available to
+the adapter.
+
+Virtualized Environments
+------------------------
+1. Disable XPS on both ends by using the included virt_perf_default script
+or by running the following command as root::
+
+ for file in `ls /sys/class/net/<ethX>/queues/tx-*/xps_cpus`;
+ do echo 0 > $file; done
+
+2. Using the appropriate mechanism (vcpupin) in the vm, pin the cpu's to
+individual lcpu's, making sure to use a set of cpu's included in the
+device's local_cpulist: /sys/class/net/<ethX>/device/local_cpulist.
+
+3. Configure as many Rx/Tx queues in the VM as available. Do not rely on
+the default setting of 1.
+
+
+Non-virtualized Environments
+----------------------------
+Pin the adapter's IRQs to specific cores by disabling the irqbalance service
+and using the included set_irq_affinity script. Please see the script's help
+text for further options.
+
+- The following settings will distribute the IRQs across all the cores evenly::
+
+ # scripts/set_irq_affinity -x all <interface1> , [ <interface2>, ... ]
+
+- The following settings will distribute the IRQs across all the cores that are
+ local to the adapter (same NUMA node)::
+
+ # scripts/set_irq_affinity -x local <interface1> ,[ <interface2>, ... ]
+
+For very CPU intensive workloads, we recommend pinning the IRQs to all cores.
+
+For IP Forwarding: Disable Adaptive ITR and lower Rx and Tx interrupts per
+queue using ethtool.
+
+- Setting rx-usecs and tx-usecs to 125 will limit interrupts to about 8000
+ interrupts per second per queue.
+
+::
+
+ # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 125 \
+ tx-usecs 125
+
+For lower CPU utilization: Disable Adaptive ITR and lower Rx and Tx interrupts
+per queue using ethtool.
+
+- Setting rx-usecs and tx-usecs to 250 will limit interrupts to about 4000
+ interrupts per second per queue.
+
+::
+
+ # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 250 \
+ tx-usecs 250
+
+For lower latency: Disable Adaptive ITR and ITR by setting Rx and Tx to 0 using
+ethtool.
+
+::
+
+ # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 0 \
+ tx-usecs 0
+
+Application Device Queues (ADq)
+-------------------------------
+Application Device Queues (ADq) allows you to dedicate one or more queues to a
+specific application. This can reduce latency for the specified application,
+and allow Tx traffic to be rate limited per application. Follow the steps below
+to set ADq.
+
+1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
+The shaper bw_rlimit parameter is optional.
+
+Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
+to 1Gbit for tc0 and 3Gbit for tc1.
+
+::
+
+ # tc qdisc add dev <interface> root mqprio num_tc 2 map 0 0 0 0 1 1 1 1
+ queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
+ max_rate 1Gbit 3Gbit
+
+map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
+sets priorities 0-3 to use tc0 and 4-7 to use tc1)
+
+queues: for each tc, <num queues>@<offset> (e.g. queues 16@0 16@16 assigns
+16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
+number of queues for all tcs is 64 or number of cores, whichever is lower.)
+
+hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
+offload mode in mqprio that makes full use of the mqprio options, the
+TCs, the queue configurations, and the QoS parameters.
+
+shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
+Totals must be equal or less than port speed.
+
+For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
+monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
+
+2. Enable HW TC offload on interface::
+
+ # ethtool -K <interface> hw-tc-offload on
+
+3. Apply TCs to ingress (RX) flow of interface::
+
+ # tc qdisc add dev <interface> ingress
+
+NOTES:
+ - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory.
+ - ADq is not compatible with cloud filters.
+ - Setting up channels via ethtool (ethtool -L) is not supported when the
+ TCs are configured using mqprio.
+ - You must have iproute2 latest version
+ - NVM version 6.01 or later is required.
+ - ADq cannot be enabled when any the following features are enabled: Data
+ Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband
+ Filters.
+ - If another driver (for example, DPDK) has set cloud filters, you cannot
+ enable ADq.
+ - Tunnel filters are not supported in ADq. If encapsulated packets do
+ arrive in non-tunnel mode, filtering will be done on the inner headers.
+ For example, for VXLAN traffic in non-tunnel mode, PCTYPE is identified
+ as a VXLAN encapsulated packet, outer headers are ignored. Therefore,
+ inner headers are matched.
+ - If a TC filter on a PF matches traffic over a VF (on the PF), that
+ traffic will be routed to the appropriate queue of the PF, and will
+ not be passed on the VF. Such traffic will end up getting dropped higher
+ up in the TCP/IP stack as it does not match PF address data.
+ - If traffic matches multiple TC filters that point to different TCs,
+ that traffic will be duplicated and sent to all matching TC queues.
+ The hardware switch mirrors the packet to a VSI list when multiple
+ filters are matched.
+
+
+Known Issues/Troubleshooting
+============================
+
+NOTE: 1 Gb devices based on the Intel(R) Ethernet Network Connection X722 do
+not support the following features:
+
+ * Data Center Bridging (DCB)
+ * QOS
+ * VMQ
+ * SR-IOV
+ * Task Encapsulation offload (VXLAN, NVGRE)
+ * Energy Efficient Ethernet (EEE)
+ * Auto-media detect
+
+Unexpected Issues when the device driver and DPDK share a device
+----------------------------------------------------------------
+Unexpected issues may result when an i40e device is in multi driver mode and
+the kernel driver and DPDK driver are sharing the device. This is because
+access to the global NIC resources is not synchronized between multiple
+drivers. Any change to the global NIC configuration (writing to a global
+register, setting global configuration by AQ, or changing switch modes) will
+affect all ports and drivers on the device. Loading DPDK with the
+"multi-driver" module parameter may mitigate some of the issues.
+
+TC0 must be enabled when setting up DCB on a switch
+---------------------------------------------------
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.

-Identifying Your Adapter
-========================
-
-The driver in this release is compatible with the Intel Ethernet
-Controller XL710 Family.
-
-For more information on how to identify your adapter, go to the Adapter &
-Driver ID Guide at:
-
- http://support.intel.com/support/network/sb/CS-012904.htm
-
-
-Enabling the driver
-===================
-
-The driver is enabled via the standard kernel configuration system,
-using the make command:
-
- make config/oldconfig/menuconfig/etc.
-
-The driver is located in the menu structure at:
-
- -> Device Drivers
- -> Network device support (NETDEVICES [=y])
- -> Ethernet driver support
- -> Intel devices
- -> Intel(R) Ethernet Controller XL710 Family
-
-Additional Configurations
-=========================
-
- Generic Receive Offload (GRO)
- -----------------------------
- The driver supports the in-kernel software implementation of GRO. GRO has
- shown that by coalescing Rx traffic into larger chunks of data, CPU
- utilization can be significantly reduced when under large Rx load. GRO is
- an evolution of the previously-used LRO interface. GRO is able to coalesce
- other protocols besides TCP. It's also safe to use with configurations that
- are problematic for LRO, namely bridging and iSCSI.
-
- Ethtool
- -------
- The driver utilizes the ethtool interface for driver configuration and
- diagnostics, as well as displaying statistical information. The latest
- ethtool version is required for this functionality.
-
- The latest release of ethtool can be found from
- https://www.kernel.org/pub/software/network/ethtool
-
-
- Flow Director n-ntuple traffic filters (FDir)
- ---------------------------------------------
- The driver utilizes the ethtool interface for configuring ntuple filters,
- via "ethtool -N <device> <filter>".
-
- The sctp4, ip4, udp4, and tcp4 flow types are supported with the standard
- fields including src-ip, dst-ip, src-port and dst-port. The driver only
- supports fully enabling or fully masking the fields, so use of the mask
- fields for partial matches is not supported.
-
- Additionally, the driver supports using the action to specify filters for a
- Virtual Function. You can specify the action as a 64bit value, where the
- lower 32 bits represents the queue number, while the next 8 bits represent
- which VF. Note that 0 is the PF, so the VF identifier is offset by 1. For
- example:
-
- ... action 0x800000002 ...
-
- Would indicate to direct traffic for Virtual Function 7 (8 minus 1) on queue
- 2 of that VF.
-
- The driver also supports using the user-defined field to specify 2 bytes of
- arbitrary data to match within the packet payload in addition to the regular
- fields. The data is specified in the lower 32bits of the user-def field in
- the following way:
-
- +----------------------------+---------------------------+
- | 31 28 24 20 16 | 15 12 8 4 0|
- +----------------------------+---------------------------+
- | offset into packet payload | 2 bytes of flexible data |
- +----------------------------+---------------------------+
-
- As an example,
-
- ... user-def 0x4FFFF ....
-
- means to match the value 0xFFFF 4 bytes into the packet payload. Note that
- the offset is based on the beginning of the payload, and not the beginning
- of the packet. Thus
-
- flow-type tcp4 ... user-def 0x8BEAF ....
-
- would match TCP/IPv4 packets which have the value 0xBEAF 8bytes into the
- TCP/IPv4 payload.
-
- For ICMP, the hardware parses the ICMP header as 4 bytes of header and 4
- bytes of payload, so if you want to match an ICMP frames payload you may need
- to add 4 to the offset in order to match the data.
-
- Furthermore, the offset can only be up to a value of 64, as the hardware
- will only read up to 64 bytes of data from the payload. It must also be even
- as the flexible data is 2 bytes long and must be aligned to byte 0 of the
- packet payload.
-
- When programming filters, the hardware is limited to using a single input
- set for each flow type. This means that it is an error to program two
- different filters with the same type that don't match on the same fields.
- Thus the second of the following two commands will fail:
-
- ethtool -N <device> flow-type tcp4 src-ip 192.168.0.7 action 5
- ethtool -N <device> flow-type tcp4 dst-ip 192.168.15.18 action 1
-
- This is because the first filter will be accepted and reprogram the input
- set for TCPv4 filters, but the second filter will be unable to reprogram the
- input set until all the conflicting TCPv4 filters are first removed.
-
- Note that the user-defined flexible offset is also considered part of the
- input set and cannot be programmed separately for multiple filters of the
- same type. However, the flexible data is not part of the input set and
- multiple filters may use the same offset but match against different data.
-
- Data Center Bridging (DCB)
- --------------------------
- DCB configuration is not currently supported.
-
- FCoE
- ----
- The driver supports Fiber Channel over Ethernet (FCoE) and Data Center
- Bridging (DCB) functionality. Configuring DCB and FCoE is outside the scope
- of this driver doc. Refer to http://www.open-fcoe.org/ for FCoE project
- information and http://www.open-lldp.org/ or email list
- e1000-eedc@lists.sourceforge.net for DCB information.
-
- MAC and VLAN anti-spoofing feature
- ----------------------------------
- When a malicious driver attempts to send a spoofed packet, it is dropped by
- the hardware and not transmitted. An interrupt is sent to the PF driver
- notifying it of the spoof attempt.
-
- When a spoofed packet is detected the PF driver will send the following
- message to the system log (displayed by the "dmesg" command):
-
- Spoof event(s) detected on VF (n)
-
- Where n=the VF that attempted to do the spoofing.
-

+- Known Issues/Troubleshooting
+- Support
+
+This file describes the iavf Linux* Base Driver. This driver was formerly
+called i40evf.
+
+The iavf driver supports the below mentioned virtual function devices and
+can only be activated on kernels running the i40e or newer Physical Function
+(PF) driver compiled with CONFIG_PCI_IOV. The iavf driver requires
+CONFIG_PCI_MSI to be enabled.
+
+The guest OS loading the iavf driver must support MSI-X interrupts.
+
+Identifying Your Adapter
+========================
+The driver in this kernel is compatible with devices based on the following:
+ * Intel(R) XL710 X710 Virtual Function
+ * Intel(R) X722 Virtual Function
+ * Intel(R) XXV710 Virtual Function
+ * Intel(R) Ethernet Adaptive Virtual Function
+
+For the best performance, make sure the latest NVM/FW is installed on your
+device.
+
+For information on how to identify your adapter, and for the latest NVM/FW
+images and Intel network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+
+Additional Features and Configurations
+======================================
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+ dmesg -n 8
+
+NOTE: This setting is not saved across reboots.
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+Setting VLAN Tag Stripping
+--------------------------
+If you have applications that require Virtual Functions (VFs) to receive
+packets with VLAN tags, you can disable VLAN tag stripping for the VF. The
+Physical Function (PF) processes requests issued from the VF to enable or
+disable VLAN tag stripping. Note that if the PF has assigned a VLAN to a VF,
+then requests from that VF to set VLAN tag stripping will be ignored.
+
+To enable/disable VLAN tag stripping for a VF, issue the following command
+from inside the VM in which you are running the VF::
+
+ ethtool -K <if_name> rxvlan on/off
+
+or alternatively::
+
+ ethtool --offload <if_name> rxvlan on/off
+
+Adaptive Virtual Function
+-------------------------
+Adaptive Virtual Function (AVF) allows the virtual function driver, or VF, to
+adapt to changing feature sets of the physical function driver (PF) with which
+it is associated. This allows system administrators to update a PF without
+having to update all the VFs associated with it. All AVFs have a single common
+device ID and branding string.
+
+AVFs have a minimum set of features known as "base mode," but may provide
+additional features depending on what features are available in the PF with
+which the AVF is associated. The following are base mode features:
+
+- 4 Queue Pairs (QP) and associated Configuration Status Registers (CSRs)
+ for Tx/Rx.
+- i40e descriptors and ring format.
+- Descriptor write-back completion.
+- 1 control queue, with i40e descriptors, CSRs and ring format.
+- 5 MSI-X interrupt vectors and corresponding i40e CSRs.
+- 1 Interrupt Throttle Rate (ITR) index.
+- 1 Virtual Station Interface (VSI) per VF.
+- 1 Traffic Class (TC), TC0
+- Receive Side Scaling (RSS) with 64 entry indirection table and key,
+ configured through the PF.
+- 1 unicast MAC address reserved per VF.
+- 16 MAC address filters for each VF.
+- Stateless offloads - non-tunneled checksums.
+- AVF device ID.
+- HW mailbox is used for VF to PF communications (including on Windows).
+
+IEEE 802.1ad (QinQ) Support
+---------------------------
+The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
+IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
+"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
+allow L2 tunneling and the ability to segregate traffic within a particular
+VLAN ID, among other uses.
+
+The following are examples of how to configure 802.1ad (QinQ)::
+
+ ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
+ ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
+
+Where "24" and "371" are example VLAN IDs.
+
+NOTES:
+ Receive checksum offloads, cloud filters, and VLAN acceleration are not
+ supported for 802.1ad (QinQ) packets.
+
+Application Device Queues (ADq)
+-------------------------------
+Application Device Queues (ADq) allows you to dedicate one or more queues to a
+specific application. This can reduce latency for the specified application,
+and allow Tx traffic to be rate limited per application. Follow the steps below
+to set ADq.
+
+1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
+The shaper bw_rlimit parameter is optional.
+
+Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
+to 1Gbit for tc0 and 3Gbit for tc1.
+
+::
+
+ # tc qdisc add dev <interface> root mqprio num_tc 2 map 0 0 0 0 1 1 1 1
+ queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
+ max_rate 1Gbit 3Gbit
+
+map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
+sets priorities 0-3 to use tc0 and 4-7 to use tc1)
+
+queues: for each tc, <num queues>@<offset> (e.g. queues 16@0 16@16 assigns
+16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
+number of queues for all tcs is 64 or number of cores, whichever is lower.)
+
+hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
+offload mode in mqprio that makes full use of the mqprio options, the
+TCs, the queue configurations, and the QoS parameters.
+
+shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
+Totals must be equal or less than port speed.
+
+For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
+monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
+
+2. Enable HW TC offload on interface::
+
+ # ethtool -K <interface> hw-tc-offload on
+
+3. Apply TCs to ingress (RX) flow of interface::
+
+ # tc qdisc add dev <interface> ingress
+
+NOTES:
+ - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory.
+ - ADq is not compatible with cloud filters.
+ - Setting up channels via ethtool (ethtool -L) is not supported when the TCs
+ are configured using mqprio.
+ - You must have iproute2 latest version
+ - NVM version 6.01 or later is required.
+ - ADq cannot be enabled when any the following features are enabled: Data
+ Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband Filters.
+ - If another driver (for example, DPDK) has set cloud filters, you cannot
+ enable ADq.
+ - Tunnel filters are not supported in ADq. If encapsulated packets do arrive
+ in non-tunnel mode, filtering will be done on the inner headers. For example,
+ for VXLAN traffic in non-tunnel mode, PCTYPE is identified as a VXLAN
+ encapsulated packet, outer headers are ignored. Therefore, inner headers are
+ matched.
+ - If a TC filter on a PF matches traffic over a VF (on the PF), that traffic
+ will be routed to the appropriate queue of the PF, and will not be passed on
+ the VF. Such traffic will end up getting dropped higher up in the TCP/IP
+ stack as it does not match PF address data.
+ - If traffic matches multiple TC filters that point to different TCs, that
+ traffic will be duplicated and sent to all matching TC queues. The hardware
+ switch mirrors the packet to a VSI list when multiple filters are matched.
+
+
+Known Issues/Troubleshooting
+============================
+
+Traffic Is Not Being Passed Between VM and Client
+-------------------------------------------------
+You may not be able to pass traffic between a client system and a
+Virtual Machine (VM) running on a separate host if the Virtual Function
+(VF, or Virtual NIC) is not in trusted mode and spoof checking is enabled
+on the VF. Note that this situation can occur in any combination of client,
+host, and guest operating system. For information on how to set the VF to
+trusted mode, refer to the section "VLAN Tag Packet Steering" in this
+readme document. For information on setting spoof checking, refer to the
+section "MAC and VLAN anti-spoofing feature" in this readme document.
+
+Do not unload port driver if VF with active VM is bound to it
+-------------------------------------------------------------
+Do not unload a port's driver if a Virtual Function (VF) with an active Virtual
+Machine (VM) is bound to it. Doing so will cause the port to appear to hang.
+Once the VM shuts down, or otherwise releases the VF, the command will complete.
+
+Virtual machine does not get link
+---------------------------------
+If the virtual machine has more than one virtual port assigned to it, and those
+virtual ports are bound to different physical ports, you may not get link on
+all of the virtual ports. The following command may work around the issue::
+
+ ethtool -r <PF>
+
+Where <PF> is the PF interface in the host, for example: p5p1. You may need to
+run the command more than once to get link on all virtual ports.
+
+MAC address of Virtual Function changes unexpectedly
+----------------------------------------------------
+If a Virtual Function's MAC address is not assigned in the host, then the VF
+(virtual function) driver will use a random MAC address. This random MAC
+address may change each time the VF driver is reloaded. You can assign a static
+MAC address in the host machine. This static MAC address will survive
+a VF driver reload.
+
+Driver Buffer Overflow Fix
+--------------------------
+The fix to resolve CVE-2016-8105, referenced in Intel SA-00069
+https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00069.html
+is included in this and future versions of the driver.
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+Due to the default ARP behavior on Linux, it is not possible to have one system
+on two IP networks in the same Ethernet broadcast domain (non-partitioned
+switch) behave as expected. All Ethernet interfaces will respond to IP traffic
+for any IP address assigned to the system. This results in unbalanced receive
+traffic.
+
+If you have multiple interfaces in a server, either turn on ARP filtering by
+entering::
+
+ echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+
+NOTE: This setting is not saved across reboots. The configuration change can be
+made permanent by adding the following line to the file /etc/sysctl.conf::
+
+ net.ipv4.conf.all.arp_filter = 1
+
+Another alternative is to install the interfaces in separate broadcast domains
+(either in different switches or in a switch partitioned to VLANs).
+
+Rx Page Allocation Errors
+-------------------------
+'Page allocation failure. order:0' errors may occur under stress.
+This is caused by the way the Linux kernel reports this stressed condition.

+Identifying Your Adapter
+========================
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+
+Command Line Parameters
+========================
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax::
+
+ modprobe igb [<option>=<VAL1>,<VAL2>,...]
+
+There needs to be a <VAL#> for each network port in the system supported by
+this driver. The values will be applied to each instance, in function order.
+For example::
+
+ modprobe igb max_vfs=2,4
+
+In this case, there are two network ports supported by igb in the system.
+
+NOTE: A descriptor describes a data buffer and attributes related to the data
+buffer. This information is accessed by the hardware.
+
+max_vfs
+-------
+:Valid Range: 0-7
+
+This parameter adds support for SR-IOV. It causes the driver to spawn up to
+max_vfs worth of virtual functions. If the value is greater than 0 it will
+also force the VMDq parameter to be 1 or more.
+
+The parameters for the driver are referenced by position. Thus, if you have a
+dual port adapter, or more than one adapter in your system, and want N virtual
+functions per port, you must specify a number for each port with each parameter
+separated by a comma. For example::
+
+ modprobe igb max_vfs=4
+
+This will spawn 4 VFs on the first port.
+
+::
+
+ modprobe igb max_vfs=2,4
+
+This will spawn 2 VFs on the first port and 4 VFs on the second port.
+
+NOTE: Caution must be used in loading the driver with these parameters.
+Depending on your system configuration, number of slots, etc., it is impossible
+to predict in all cases where the positions would be on the command line.
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
+and VLAN tag stripping/insertion will remain enabled. Please remove the old
+VLAN filter before the new VLAN filter is added. For example::
+
+ ip link set eth0 vf 0 vlan 100 // set vlan 100 for VF 0
+ ip link set eth0 vf 0 vlan 0 // Delete vlan 100
+ ip link set eth0 vf 0 vlan 200 // set a new vlan 200 for VF 0
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level debug messages displayed in the system logs.
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+ ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+ ip link set mtu 9000 dev eth<x>
+ ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9216. This value coincides
+with the maximum Jumbo Frames size of 9234 bytes.
+
+NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
+poor performance or loss of link.
+
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+
+https://www.kernel.org/pub/software/network/ethtool/
+
+
+Enabling Wake on LAN* (WoL)
+---------------------------
+WoL is configured through the ethtool* utility.
+
+WoL will be enabled on the system during the next shut down or reboot. For
+this driver version, in order to enable WoL, the igb driver must be loaded
+prior to shutting down or suspending the system.
+
+NOTE: Wake on LAN is only supported on port A of multi-port devices. Also
+Wake On LAN is not supported for the following device:
+- Intel(R) Gigabit VT Quad Port Server Adapter
+
+
+Multiqueue
+----------
+In this mode, a separate MSI-X vector is allocated for each queue and one for
+"other" interrupts such as link status change and errors. All interrupts are
+throttled via interrupt moderation. Interrupt moderation must be used to avoid
+interrupt storms while the driver is processing one interrupt. The moderation
+value should be at least as large as the expected time for the driver to
+process an interrupt. Multiqueue is off by default.
+
+REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not found,
+the system will fallback to MSI or to Legacy interrupts. This driver supports
+receive multiqueue on all kernels that support MSI-X.
+
+NOTE: On some kernels a reboot is required to switch between single queue mode
+and multiqueue mode or vice-versa.
+
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+
+An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
+spoofed packet is detected, the PF driver will send the following message to
+the system log (displayed by the "dmesg" command):
+Spoof event(s) detected on VF(n), where n = the VF that attempted to do the
+spoofing
+
+
+Setting MAC Address, VLAN and Rate Limit Using IProute2 Tool
+------------------------------------------------------------
+You can set a MAC address of a Virtual Function (VF), a default VLAN and the
+rate limit using the IProute2 tool. Download the latest version of the
+IProute2 tool from Sourceforge if your version does not have all the features
+you require.

+
+In This Release
+===============
+
+This file describes the ixgb Linux Base Driver for the 10 Gigabit Intel(R)
+Network Connection. This driver includes support for Itanium(R)2-based
+systems.
+
+For questions related to hardware requirements, refer to the documentation
+supplied with your 10 Gigabit adapter. All hardware requirements listed apply
+to use with Linux.
+
+The following features are available in this kernel:
+ - Native VLANs
+ - Channel Bonding (teaming)
+ - SNMP
+
+Channel Bonding documentation can be found in the Linux kernel source:
+/Documentation/networking/bonding.txt
+
+The driver information previously displayed in the /proc filesystem is not
+supported in this release. Alternatively, you can use ethtool (version 1.6
+or later), lspci, and iproute2 to obtain the same information.
+
+Instructions on updating ethtool can be found in the section "Additional
+Configurations" later in this document.
+
+
+Identifying Your Adapter
+========================
+
+The following Intel network adapters are compatible with the drivers in this
+release:
+
++------------+------------------------------+----------------------------------+
+| Controller | Adapter Name | Physical Layer |
++============+==============================+==================================+
+| 82597EX | Intel(R) PRO/10GbE LR/SR/CX4 | - 10G Base-LR (fiber) |
+| | Server Adapters | - 10G Base-SR (fiber) |
+| | | - 10G Base-CX4 (copper) |
++------------+------------------------------+----------------------------------+
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+
+ https://support.intel.com
+
+
+Command Line Parameters
+=======================
+
+If the driver is built as a module, the following optional parameters are
+used by entering them on the command line with the modprobe command using
+this syntax::
+
+ modprobe ixgb [<option>=<VAL1>,<VAL2>,...]
+
+For example, with two 10GbE PCI adapters, entering::
+
+ modprobe ixgb TxDescriptors=80,128
+
+loads the ixgb driver with 80 TX resources for the first adapter and 128 TX
+resources for the second adapter.
+
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+Copybreak
+---------
+:Valid Range: 0-XXXX
+:Default Value: 256
+
+ This is the maximum size of packet that is copied to a new buffer on
+ receive.
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+ This parameter adjusts the level of debug messages displayed in the
+ system logs.
+
+FlowControl
+-----------
+:Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
+:Default Value: 1 if no EEPROM, otherwise read from EEPROM
+
+ This parameter controls the automatic generation(Tx) and response(Rx) to
+ Ethernet PAUSE frames. There are hardware bugs associated with enabling
+ Tx flow control so beware.
+
+RxDescriptors
+-------------
+:Valid Range: 64-4096
+:Default Value: 1024
+
+ This value is the number of receive descriptors allocated by the driver.
+ Increasing this value allows the driver to buffer more incoming packets.
+ Each descriptor is 16 bytes. A receive buffer is also allocated for
+ each descriptor and can be either 2048, 4056, 8192, or 16384 bytes,
+ depending on the MTU setting. When the MTU size is 1500 or less, the
+ receive buffer size is 2048 bytes. When the MTU is greater than 1500 the
+ receive buffer size will be either 4056, 8192, or 16384 bytes. The
+ maximum MTU size is 16114.
+
+TxDescriptors
+-------------
+:Valid Range: 64-4096
+:Default Value: 256
+
+ This value is the number of transmit descriptors allocated by the driver.
+ Increasing this value allows the driver to queue more transmits. Each
+ descriptor is 16 bytes.
+
+RxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 72
+
+ This value delays the generation of receive interrupts in units of
+ 0.8192 microseconds. Receive interrupt reduction can improve CPU
+ efficiency if properly tuned for specific network traffic. Increasing
+ this value adds extra latency to frame reception and can end up
+ decreasing the throughput of TCP traffic. If the system is reporting
+ dropped receives, this value may be set too high, causing the driver to
+ run out of available receive descriptors.
+
+TxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 32
+
+ This value delays the generation of transmit interrupts in units of
+ 0.8192 microseconds. Transmit interrupt reduction can improve CPU
+ efficiency if properly tuned for specific network traffic. Increasing
+ this value adds extra latency to frame transmission and can end up
+ decreasing the throughput of TCP traffic. If this value is set too high,
+ it will cause the driver to run out of available transmit descriptors.
+
+XsumRX
+------
+:Valid Range: 0-1
+:Default Value: 1
+
+ A value of '1' indicates that the driver should enable IP checksum
+ offload for received packets (both UDP and TCP) to the adapter hardware.
+
+RxFCHighThresh
+--------------
+:Valid Range: 1,536-262,136 (0x600 - 0x3FFF8, 8 byte granularity)
+:Default Value: 196,608 (0x30000)
+
+ Receive Flow control high threshold (when we send a pause frame)
+
+RxFCLowThresh
+-------------
+:Valid Range: 64-262,136 (0x40 - 0x3FFF8, 8 byte granularity)
+:Default Value: 163,840 (0x28000)
+
+ Receive Flow control low threshold (when we send a resume frame)
+
+FCReqTimeout
+------------
+:Valid Range: 1-65535
+:Default Value: 65535
+
+ Flow control request timeout (how long to pause the link partner's tx)
+
+IntDelayEnable
+--------------
+:Value Range: 0,1
+:Default Value: 1
+
+ Interrupt Delay, 0 disables transmit interrupt delay and 1 enables it.
+
+
+Improving Performance
+=====================
+
+With the 10 Gigabit server adapters, the default Linux configuration will
+very likely limit the total available throughput artificially. There is a set
+of configuration changes that, when applied together, will increase the ability
+of Linux to transmit and receive data. The following enhancements were
+originally acquired from settings published at http://www.spec.org/web99/ for
+various submitted results using Linux.
+
+NOTE:
+ These changes are only suggestions, and serve as a starting point for
+ tuning your network performance.
+
+The changes are made in three major ways, listed in order of greatest effect:
+
+- Use ip link to modify the mtu (maximum transmission unit) and the txqueuelen
+ parameter.
+- Use sysctl to modify /proc parameters (essentially kernel tuning)
+- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
+ transmit burst lengths on the bus.
+
+NOTE:
+ setpci modifies the adapter's configuration registers to allow it to read
+ up to 4k bytes at a time (for transmits). However, for some systems the
+ behavior after modifying this register may be undefined (possibly errors of
+ some kind). A power-cycle, hard reset or explicitly setting the e6 register
+ back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a
+ stable configuration.
+
+- COPY these lines and paste them into ixgb_perf.sh:
+
+::
+
+ #!/bin/bash
+ echo "configuring network performance , edit this file to change the interface

+
+- COPY these lines and paste them into sysctl_ixgb.conf:

+
+ # some of the defaults may be different for your kernel
+ # call this file with sysctl -p <this file>
+ # these are just suggested values that worked well to increase throughput in
+ # several network benchmark tests, your mileage may vary
+
+ ### IPV4 specific settings
+ # turn TCP timestamp support off, default 1, reduces CPU use
+ net.ipv4.tcp_timestamps = 0
+ # turn SACK support off, default on
+ # on systems with a VERY fast bus -> memory interface this is the big gainer
+ net.ipv4.tcp_sack = 0
+ # set min/default/max TCP read buffer, default 4096 87380 174760
+ net.ipv4.tcp_rmem = 10000000 10000000 10000000
+ # set min/pressure/max TCP write buffer, default 4096 16384 131072
+ net.ipv4.tcp_wmem = 10000000 10000000 10000000
+ # set min/pressure/max TCP buffer space, default 31744 32256 32768
+ net.ipv4.tcp_mem = 10000000 10000000 10000000
+
+ ### CORE settings (mostly for socket and UDP effect)
+ # set maximum receive socket buffer size, default 131071
+ net.core.rmem_max = 524287
+ # set maximum send socket buffer size, default 131071

+ # set number of unprocessed input packets before kernel starts dropping them; default 300
+ net.core.netdev_max_backlog = 300000
+
+Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface
+your ixgb driver is using and/or replace '1a48' with appropriate 10GbE device's
+ID installed on the system.
+
+NOTE:
+ Unless these scripts are added to the boot process, these changes will
+ only last only until the next system reboot.
+
+
+Resolving Slow UDP Traffic
+--------------------------
+If your server does not seem to be able to receive UDP traffic as fast as it
+can receive TCP traffic, it could be because Linux, by default, does not set
+the network stack buffers as large as they need to be to support high UDP
+transfer rates. One way to alleviate this problem is to allow more memory to
+be used by the IP stack to store incoming data.
+
+For instance, use the commands::
+
+ sysctl -w net.core.rmem_max=262143
+
+and::
+
+ sysctl -w net.core.rmem_default=262143
+
+to increase the read buffer memory max and default to 262143 (256k - 1) from
+defaults of max=131071 (128k - 1) and default=65535 (64k - 1). These variables
+will increase the amount of memory used by the network stack for receives, and
+can be increased significantly more if necessary for your application.
+
+
+Additional Configurations
+=========================
+
+Configuring the Driver on Different Distributions
+-------------------------------------------------
+Configuring a network driver to load properly when the system is started is
+distribution dependent. Typically, the configuration process involves adding
+an alias line to /etc/modprobe.conf as well as editing other system startup
+scripts and/or configuration files. Many popular Linux distributions ship
+with tools to make these changes for you. To learn the proper way to
+configure a network device for your system, refer to your distribution
+documentation. If during this process you are asked for the driver or module
+name, the name for the Linux Base Driver for the Intel 10GbE Family of
+Adapters is ixgb.
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+ dmesg -n 8
+
+NOTE: This setting is not saved across reboots.
+
+Jumbo Frames
+------------
+The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
+enabled by changing the MTU to a value larger than the default of 1500.
+The maximum value for the MTU is 16114. Use the ip command to
+increase the MTU size. For example::
+
+ ip li set dev ethx mtu 9000
+
+The maximum MTU setting for Jumbo Frames is 16114. This value coincides
+with the maximum Jumbo Frames size of 16128.
+
+Ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The ethtool
+version 1.6 or later is required for this functionality.
+
+The latest release of ethtool can be found from
+https://www.kernel.org/pub/software/network/ethtool/
+
+NOTE:
+ The ethtool version 1.6 only supports a limited set of ethtool options.
+ Support for a more complete ethtool feature set can be enabled by
+ upgrading to the latest version.
+
+NAPI
+----
+NAPI (Rx polling mode) is supported in the ixgb driver.
+
+See https://wiki.linuxfoundation.org/networking/napi for more information on
+NAPI.
+
+
+Known Issues/Troubleshooting
+============================
+
+NOTE:
+ After installing the driver, if your Intel Network Connection is not
+ working, verify in the "In This Release" section of the readme that you have
+ installed the correct driver.
+
+Cable Interoperability Issue with Fujitsu XENPAK Module in SmartBits Chassis
+----------------------------------------------------------------------------
+Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
+Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
+chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
+The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
+Server adapter or the SmartBits. If this situation occurs using a different
+cable assembly may resolve the issue.
+
+Cable Interoperability Issues with HP Procurve 3400cl Switch Port
+-----------------------------------------------------------------
+Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
+adapter is connected to an HP Procurve 3400cl switch port using short cables
+(1 m or shorter). If this situation occurs, using a longer cable may resolve
+the issue.
+
+Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
+Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
+errors may be received either by the CX4 Server adapter or at the switch. If
+this situation occurs, using a different cable assembly may resolve the issue.
+
+Jumbo Frames System Requirement
+-------------------------------
+Memory allocation failures have been observed on Linux systems with 64 MB
+of RAM or less that are running Jumbo Frames. If you are using Jumbo
+Frames, your system may require more than the advertised minimum
+requirement of 64 MB of system memory.
+
+Performance Degradation with Jumbo Frames
+-----------------------------------------
+Degradation in throughput performance may be observed in some Jumbo frames
+environments. If this is observed, increasing the application's socket buffer
+size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
+See the specific application manual and /usr/src/linux*/Documentation/
+networking/ip-sysctl.txt for more details.
+
+Allocating Rx Buffers when Using Jumbo Frames
+---------------------------------------------
+Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
+the available memory is heavily fragmented. This issue may be seen with PCI-X
+adapters or with packet split disabled. This can be reduced or eliminated
+by changing the amount of available memory for receive buffer allocation, by
+increasing /proc/sys/vm/min_free_kbytes.
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+Due to the default ARP behavior on Linux, it is not possible to have
+one system on two IP networks in the same Ethernet broadcast domain
+(non-partitioned switch) behave as expected. All Ethernet interfaces
+will respond to IP traffic for any IP address assigned to the system.
+This results in unbalanced receive traffic.
+
+If you have multiple interfaces in a server, do either of the following:
+
+ - Turn on ARP filtering by entering::
+
+ echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+
+ - Install the interfaces in separate broadcast domains - either in
+ different switches or in a switch partitioned to VLANs.
+
+UDP Stress Test Dropped Packet Issue
+--------------------------------------
+Under small packets UDP stress test with 10GbE driver, the Linux system
+may drop UDP packets due to the fullness of socket buffers. You may want
+to change the driver's Flow Control variables to the minimum value for
+controlling packet reception.
+
+Tx Hangs Possible Under Stress
+------------------------------
+Under stress conditions, if TX hangs occur, turning off TSO
+"ethtool -K eth0 tso off" may resolve the problem.

-
-In This Release
-===============
-
-This file describes the ixgb Linux Base Driver for the 10 Gigabit Intel(R)
-Network Connection. This driver includes support for Itanium(R)2-based
-systems.
-
-For questions related to hardware requirements, refer to the documentation
-supplied with your 10 Gigabit adapter. All hardware requirements listed apply
-to use with Linux.
-
-The following features are available in this kernel:
- - Native VLANs
- - Channel Bonding (teaming)
- - SNMP
-
-Channel Bonding documentation can be found in the Linux kernel source:
-/Documentation/networking/bonding.txt
-
-The driver information previously displayed in the /proc filesystem is not
-supported in this release. Alternatively, you can use ethtool (version 1.6
-or later), lspci, and iproute2 to obtain the same information.
-
-Instructions on updating ethtool can be found in the section "Additional
-Configurations" later in this document.
-
-
-Identifying Your Adapter
-========================
-
-The following Intel network adapters are compatible with the drivers in this
-release:
-
-Controller Adapter Name Physical Layer
----------- ------------ --------------
-82597EX Intel(R) PRO/10GbE LR/SR/CX4 10G Base-LR (1310 nm optical fiber)
- Server Adapters 10G Base-SR (850 nm optical fiber)
- 10G Base-CX4(twin-axial copper cabling)
-
-For more information on how to identify your adapter, go to the Adapter &
-Driver ID Guide at:
-
- http://support.intel.com/support/network/sb/CS-012904.htm
-
-
-Building and Installation
-=========================
-
-select m for "Intel(R) PRO/10GbE support" located at:
- Location:
- -> Device Drivers
- -> Network device support (NETDEVICES [=y])
- -> Ethernet (10000 Mbit) (NETDEV_10000 [=y])
-1. make modules && make modules_install
-
-2. Load the module:
-
-    modprobe ixgb <parameter>=<value>
-
- The insmod command can be used if the full
- path to the driver module is specified. For example:
-
- insmod /lib/modules/<KERNEL VERSION>/kernel/drivers/net/ixgb/ixgb.ko
-
- With 2.6 based kernels also make sure that older ixgb drivers are
- removed from the kernel, before loading the new module:
-
- rmmod ixgb; modprobe ixgb
-
-3. Assign an IP address to the interface by entering the following, where
- x is the interface number:
-
- ip addr add ethx <IP_address>
-
-4. Verify that the interface works. Enter the following, where <IP_address>
- is the IP address for another machine on the same subnet as the interface
- that is being tested:
-
- ping <IP_address>
-
-
-Command Line Parameters
-=======================
-
-If the driver is built as a module, the following optional parameters are
-used by entering them on the command line with the modprobe command using
-this syntax:
-
- modprobe ixgb [<option>=<VAL1>,<VAL2>,...]
-
-For example, with two 10GbE PCI adapters, entering:
-
- modprobe ixgb TxDescriptors=80,128
-
-loads the ixgb driver with 80 TX resources for the first adapter and 128 TX
-resources for the second adapter.
-
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-FlowControl
-Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
-Default: Read from the EEPROM
- If EEPROM is not detected, default is 1
- This parameter controls the automatic generation(Tx) and response(Rx) to
- Ethernet PAUSE frames. There are hardware bugs associated with enabling
- Tx flow control so beware.
-
-RxDescriptors
-Valid Range: 64-512
-Default Value: 512
- This value is the number of receive descriptors allocated by the driver.
- Increasing this value allows the driver to buffer more incoming packets.
- Each descriptor is 16 bytes. A receive buffer is also allocated for
- each descriptor and can be either 2048, 4056, 8192, or 16384 bytes,
- depending on the MTU setting. When the MTU size is 1500 or less, the
- receive buffer size is 2048 bytes. When the MTU is greater than 1500 the
- receive buffer size will be either 4056, 8192, or 16384 bytes. The
- maximum MTU size is 16114.
-
-RxIntDelay
-Valid Range: 0-65535 (0=off)
-Default Value: 72
- This value delays the generation of receive interrupts in units of
- 0.8192 microseconds. Receive interrupt reduction can improve CPU
- efficiency if properly tuned for specific network traffic. Increasing
- this value adds extra latency to frame reception and can end up
- decreasing the throughput of TCP traffic. If the system is reporting
- dropped receives, this value may be set too high, causing the driver to
- run out of available receive descriptors.
-
-TxDescriptors
-Valid Range: 64-4096
-Default Value: 256
- This value is the number of transmit descriptors allocated by the driver.
- Increasing this value allows the driver to queue more transmits. Each
- descriptor is 16 bytes.
-
-XsumRX
-Valid Range: 0-1
-Default Value: 1
- A value of '1' indicates that the driver should enable IP checksum
- offload for received packets (both UDP and TCP) to the adapter hardware.
-
-
-Improving Performance
-=====================
-
-With the 10 Gigabit server adapters, the default Linux configuration will
-very likely limit the total available throughput artificially. There is a set
-of configuration changes that, when applied together, will increase the ability
-of Linux to transmit and receive data. The following enhancements were
-originally acquired from settings published at http://www.spec.org/web99/ for
-various submitted results using Linux.
-
-NOTE: These changes are only suggestions, and serve as a starting point for
- tuning your network performance.
-
-The changes are made in three major ways, listed in order of greatest effect:
-- Use ip link to modify the mtu (maximum transmission unit) and the txqueuelen
- parameter.
-- Use sysctl to modify /proc parameters (essentially kernel tuning)
-- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
- transmit burst lengths on the bus.
-
-NOTE: setpci modifies the adapter's configuration registers to allow it to read
-up to 4k bytes at a time (for transmits). However, for some systems the
-behavior after modifying this register may be undefined (possibly errors of
-some kind). A power-cycle, hard reset or explicitly setting the e6 register
-back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a
-stable configuration.
-

-# replace 1a48 with appropriate 10GbE device's ID installed on the system,
-# if needed.

-# set number of unprocessed input packets before kernel starts dropping them; default 300
-net.core.netdev_max_backlog = 300000
-- END sysctl_ixgb.conf
-
-Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface
-your ixgb driver is using and/or replace '1a48' with appropriate 10GbE device's
-ID installed on the system.
-
-NOTE: Unless these scripts are added to the boot process, these changes will
- only last only until the next system reboot.
-
-
-Resolving Slow UDP Traffic
---------------------------
-If your server does not seem to be able to receive UDP traffic as fast as it
-can receive TCP traffic, it could be because Linux, by default, does not set
-the network stack buffers as large as they need to be to support high UDP
-transfer rates. One way to alleviate this problem is to allow more memory to
-be used by the IP stack to store incoming data.
-
-For instance, use the commands:
- sysctl -w net.core.rmem_max=262143
-and
- sysctl -w net.core.rmem_default=262143
-to increase the read buffer memory max and default to 262143 (256k - 1) from
-defaults of max=131071 (128k - 1) and default=65535 (64k - 1). These variables
-will increase the amount of memory used by the network stack for receives, and
-can be increased significantly more if necessary for your application.

-
-
- NAPI
- ----

-
-Known Issues/Troubleshooting
-============================
-
- NOTE: After installing the driver, if your Intel Network Connection is not
- working, verify in the "In This Release" section of the readme that you have
- installed the correct driver.
-
- Intel(R) PRO/10GbE CX4 Server Adapter Cable Interoperability Issue with
- Fujitsu XENPAK Module in SmartBits Chassis
- ---------------------------------------------------------------------
- Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
- Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
- chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
- The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
- Server adapter or the SmartBits. If this situation occurs using a different
- cable assembly may resolve the issue.
-
- CX4 Server Adapter Cable Interoperability Issues with HP Procurve 3400cl
- Switch Port
- ------------------------------------------------------------------------
- Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
- adapter is connected to an HP Procurve 3400cl switch port using short cables
- (1 m or shorter). If this situation occurs, using a longer cable may resolve
- the issue.
-
- Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
- Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
- errors may be received either by the CX4 Server adapter or at the switch. If
- this situation occurs, using a different cable assembly may resolve the issue.
-
-
- Jumbo Frames System Requirement
- -------------------------------
- Memory allocation failures have been observed on Linux systems with 64 MB
- of RAM or less that are running Jumbo Frames. If you are using Jumbo
- Frames, your system may require more than the advertised minimum
- requirement of 64 MB of system memory.
-
-
- Performance Degradation with Jumbo Frames
- -----------------------------------------
- Degradation in throughput performance may be observed in some Jumbo frames
- environments. If this is observed, increasing the application's socket buffer
- size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
- See the specific application manual and /usr/src/linux*/Documentation/
- networking/ip-sysctl.txt for more details.
-
-
- Allocating Rx Buffers when Using Jumbo Frames
- ---------------------------------------------
- Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
- the available memory is heavily fragmented. This issue may be seen with PCI-X
- adapters or with packet split disabled. This can be reduced or eliminated
- by changing the amount of available memory for receive buffer allocation, by
- increasing /proc/sys/vm/min_free_kbytes.
-

-
- - Install the interfaces in separate broadcast domains - either in
- different switches or in a switch partitioned to VLANs.
-
-
- UDP Stress Test Dropped Packet Issue
- --------------------------------------
- Under small packets UDP stress test with 10GbE driver, the Linux system
- may drop UDP packets due to the fullness of socket buffers. You may want
- to change the driver's Flow Control variables to the minimum value for
- controlling packet reception.
-
-

- Under stress conditions, if TX hangs occur, turning off TSO
- "ethtool -K eth0 tso off" may resolve the problem.

+
+Command Line Parameters
+=======================
+
+max_vfs
+-------
+:Valid Range: 1-63
+
+This parameter adds support for SR-IOV. It causes the driver to spawn up to
+max_vfs worth of virtual functions.
+If the value is greater than 0 it will also force the VMDq parameter to be 1 or
+more.
+
+NOTE: This parameter is only used on kernel 3.7.x and below. On kernel 3.8.x
+and above, use sysfs to enable VFs. Also, for Red Hat distributions, this
+parameter is only used on version 6.6 and older. For version 6.7 and newer, use
+sysfs. For example::
+
+ #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs // enable VFs
+ #echo 0 > /sys/class/net/$dev/device/sriov_numvfs //disable VFs
+
+The parameters for the driver are referenced by position. Thus, if you have a
+dual port adapter, or more than one adapter in your system, and want N virtual
+functions per port, you must specify a number for each port with each parameter
+separated by a comma. For example::
+
+ modprobe ixgbe max_vfs=4
+
+This will spawn 4 VFs on the first port.
+
+::
+
+ modprobe ixgbe max_vfs=2,4
+
+This will spawn 2 VFs on the first port and 4 VFs on the second port.
+
+NOTE: Caution must be used in loading the driver with these parameters.
+Depending on your system configuration, number of slots, etc., it is impossible
+to predict in all cases where the positions would be on the command line.
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
+and VLAN tag stripping/insertion will remain enabled. Please remove the old
+VLAN filter before the new VLAN filter is added. For example,
+
+::
+
+ ip link set eth0 vf 0 vlan 100 // set VLAN 100 for VF 0
+ ip link set eth0 vf 0 vlan 0 // Delete VLAN 100
+ ip link set eth0 vf 0 vlan 200 // set a new VLAN 200 for VF 0
+
+With kernel 3.6, the driver supports the simultaneous usage of max_vfs and DCB
+features, subject to the constraints described below. Prior to kernel 3.6, the
+driver did not support the simultaneous operation of max_vfs greater than 0 and
+the DCB features (multiple traffic classes utilizing Priority Flow Control and
+Extended Transmission Selection).
+
+When DCB is enabled, network traffic is transmitted and received through
+multiple traffic classes (packet buffers in the NIC). The traffic is associated
+with a specific class based on priority, which has a value of 0 through 7 used
+in the VLAN tag. When SR-IOV is not enabled, each traffic class is associated
+with a set of receive/transmit descriptor queue pairs. The number of queue
+pairs for a given traffic class depends on the hardware configuration. When
+SR-IOV is enabled, the descriptor queue pairs are grouped into pools. The
+Physical Function (PF) and each Virtual Function (VF) is allocated a pool of
+receive/transmit descriptor queue pairs. When multiple traffic classes are
+configured (for example, DCB is enabled), each pool contains a queue pair from
+each traffic class. When a single traffic class is configured in the hardware,
+the pools contain multiple queue pairs from the single traffic class.
+
+The number of VFs that can be allocated depends on the number of traffic
+classes that can be enabled. The configurable number of traffic classes for
+each enabled VF is as follows:
+0 - 15 VFs = Up to 8 traffic classes, depending on device support
+16 - 31 VFs = Up to 4 traffic classes
+32 - 63 VFs = 1 traffic class
+
+When VFs are configured, the PF is allocated one pool as well. The PF supports
+the DCB features with the constraint that each traffic class will only use a
+single queue pair. When zero VFs are configured, the PF can support multiple
+queue pairs per traffic class.
+
+allow_unsupported_sfp
+---------------------
+:Valid Range: 0,1
+:Default Value: 0 (disabled)
+
+This parameter allows unsupported and untested SFP+ modules on 82599-based
+adapters, as long as the type of module is known to the driver.
+
+debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level of debug messages displayed in the system
+logs.
+
+
+Additional Features and Configurations
+======================================
+
+Flow Control
+------------
+Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
+receiving and transmitting pause frames for ixgbe. When transmit is enabled,
+pause frames are generated when the receive packet buffer crosses a predefined
+threshold. When receive is enabled, the transmit unit will halt for the time
+delay specified when a pause frame is received.
+
+NOTE: You must have a flow control capable link partner.
+
+Flow Control is enabled by default.
+
+Use ethtool to change the flow control settings. To enable or disable Rx or
+Tx Flow Control::
+
+ ethtool -A eth? rx <on|off> tx <on|off>
+
+Note: This command only enables or disables Flow Control if auto-negotiation is
+disabled. If auto-negotiation is enabled, this command changes the parameters
+used for auto-negotiation with the link partner.
+
+To enable or disable auto-negotiation::
+
+ ethtool -s eth? autoneg <on|off>
+
+Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
+on your device, you may not be able to change the auto-negotiation setting.
+
+NOTE: For 82598 backplane cards entering 1 gigabit mode, flow control default
+behavior is changed to off. Flow control in 1 gigabit mode on these devices can
+lead to transmit hangs.
+
+Intel(R) Ethernet Flow Director
+-------------------------------
+The Intel Ethernet Flow Director performs the following tasks:
+
+- Directs receive packets according to their flows to different queues.
+- Enables tight control on routing a flow in the platform.
+- Matches flows and CPU cores for flow affinity.
+- Supports multiple parameters for flexible flow classification and load
+ balancing (in SFP mode only).
+
+NOTE: Intel Ethernet Flow Director masking works in the opposite manner from
+subnet masking. In the following command::
+
+ #ethtool -N eth11 flow-type ip4 src-ip 172.4.1.2 m 255.0.0.0 dst-ip \
+ 172.21.1.1 m 255.128.0.0 action 31
+
+The src-ip value that is written to the filter will be 0.4.1.2, not 172.0.0.0
+as might be expected. Similarly, the dst-ip value written to the filter will be
+0.21.1.1, not 172.0.0.0.
+
+To enable or disable the Intel Ethernet Flow Director::
+
+ # ethtool -K ethX ntuple <on|off>
+
+When disabling ntuple filters, all the user programmed filters are flushed from
+the driver cache and hardware. All needed filters must be re-added when ntuple
+is re-enabled.
+
+To add a filter that directs packet to queue 2, use -U or -N switch::
+
+ # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+ 192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
+
+To see the list of filters currently present::
+
+ # ethtool <-u|-n> ethX
+
+Sideband Perfect Filters
+------------------------
+Sideband Perfect Filters are used to direct traffic that matches specified
+characteristics. They are enabled through ethtool's ntuple interface. To add a
+new filter use the following command::
+
+ ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
+ dst-port <port> action <queue>
+
+Where:
+ <device> - the ethernet device to program
+ <type> - can be ip4, tcp4, udp4, or sctp4
+ <ip> - the IP address to match on
+ <port> - the port number to match on
+ <queue> - the queue to direct traffic towards (-1 discards the matched traffic)
+
+Use the following command to delete a filter::
+
+ ethtool -U <device> delete <N>
+
+Where <N> is the filter id displayed when printing all the active filters, and
+may also have been specified using "loc <N>" when adding the filter.
+
+The following example matches TCP traffic sent from 192.168.0.1, port 5300,
+directed to 192.168.0.5, port 80, and sends it to queue 7::
+
+ ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
+ src-port 5300 dst-port 80 action 7
+
+For each flow-type, the programmed filters must all have the same matching
+input set. For example, issuing the following two commands is acceptable::
+
+ ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+ ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
+
+Issuing the next two commands, however, is not acceptable, since the first
+specifies src-ip and the second specifies dst-ip::
+
+ ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+ ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
+
+The second command will fail with an error. You may program multiple filters
+with the same fields, using different values, but, on one device, you may not
+program two TCP4 filters with different matching fields.
+
+Matching on a sub-portion of a field is not supported by the ixgbe driver, thus
+partial mask fields are not supported.
+
+To create filters that direct traffic to a specific Virtual Function, use the
+"user-def" parameter. Specify the user-def as a 64 bit value, where the lower 32
+bits represents the queue number, while the next 8 bits represent which VF.
+Note that 0 is the PF, so the VF identifier is offset by 1. For example::
+
+ ... user-def 0x800000002 ...
+
+specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
+that VF.
+
+Note that these filters will not break internal routing rules, and will not
+route traffic that otherwise would not have been sent to the specified Virtual
+Function.
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+ ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+ ip link set mtu 9000 dev eth<x>
+ ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file::
+
+ /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
+ /etc/sysconfig/network/<config_file> // for SLES
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9710. This value coincides
+with the maximum Jumbo Frames size of 9728 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+NOTE: For 82599-based network connections, if you are enabling jumbo frames in
+a virtual function (VF), jumbo frames must first be enabled in the physical
+function (PF). The VF MTU setting cannot be larger than the PF MTU.
+
+Generic Receive Offload, aka GRO
+--------------------------------
+The driver supports the in-kernel software implementation of GRO. GRO has
+shown that by coalescing Rx traffic into larger chunks of data, CPU
+utilization can be significantly reduced when under large Rx load. GRO is an
+evolution of the previously-used LRO interface. GRO is able to coalesce
+other protocols besides TCP. It's also safe to use with configurations that
+are problematic for LRO, namely bridging and iSCSI.
+
+Data Center Bridging (DCB)
+--------------------------
+NOTE:
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.
+
+DCB is a configuration Quality of Service implementation in hardware. It uses
+the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
+different priorities that traffic can be filtered into. It also enables
+priority flow control (802.1Qbb) which can limit or eliminate the number of
+dropped packets during network stress. Bandwidth can be allocated to each of
+these priorities, which is enforced at the hardware level (802.1Qaz).
+
+Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
+802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
+and can accept settings from a DCBX capable peer. Software configuration of
+DCBX parameters via dcbtool/lldptool are not supported.
+
+The ixgbe driver implements the DCB netlink interface layer to allow user-space
+to communicate with the driver and query DCB configuration for the port.
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+FCoE
+----
+The ixgbe driver supports Fiber Channel over Ethernet (FCoE) and Data Center
+Bridging (DCB). This code has no default effect on the regular driver
+operation. Configuring DCB and FCoE is outside the scope of this README. Refer
+to http://www.open-fcoe.org/ for FCoE project information and contact
+ixgbe-eedc@lists.sourceforge.net for DCB information.
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+
+An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
+spoofed packet is detected, the PF driver will send the following message to
+the system log (displayed by the "dmesg" command)::
+
+ ixgbe ethX: ixgbe_spoof_check: n spoofed packets detected
+
+where "x" is the PF interface number; and "n" is number of spoofed packets.
+NOTE: This feature can be disabled for a specific Virtual Function (VF)::
+
+ ip link set <pf dev> vf <vf id> spoofchk {off|on}
+

-cables are not supported.
-
-
-Flow Control
-------------
-Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
-receiving and transmitting pause frames for ixgbe. When TX is enabled, PAUSE
-frames are generated when the receive packet buffer crosses a predefined
-threshold. When rx is enabled, the transmit unit will halt for the time delay
-specified when a PAUSE frame is received.
-
-Flow Control is enabled by default. If you want to disable a flow control
-capable link partner, use ethtool:
-
- ethtool -A eth? autoneg off RX off TX off
-
-NOTE: For 82598 backplane cards entering 1 gig mode, flow control default
-behavior is changed to off. Flow control in 1 gig mode on these devices can
-lead to Tx hangs.
-
-Intel(R) Ethernet Flow Director
--------------------------------
-Supports advanced filters that direct receive packets by their flows to
-different queues. Enables tight control on routing a flow in the platform.
-Matches flows and CPU cores for flow affinity. Supports multiple parameters
-for flexible flow classification and load balancing.
-
-Flow director is enabled only if the kernel is multiple TX queue capable.
-
-An included script (set_irq_affinity.sh) automates setting the IRQ to CPU
-affinity.
-
-You can verify that the driver is using Flow Director by looking at the counter
-in ethtool: fdir_miss and fdir_match.
-
-Other ethtool Commands:
-To enable Flow Director
- ethtool -K ethX ntuple on
-To add a filter
- Use -U switch. e.g., ethtool -U ethX flow-type tcp4 src-ip 10.0.128.23
- action 1
-To see the list of filters currently present:
- ethtool -u ethX
-
-Perfect Filter: Perfect filter is an interface to load the filter table that
-funnels all flow into queue_0 unless an alternative queue is specified using
-"action". In that case, any flow that matches the filter criteria will be
-directed to the appropriate queue.
-
-If the queue is defined as -1, filter will drop matching packets.
-
-To account for filter matches and misses, there are two stats in ethtool:
-fdir_match and fdir_miss. In addition, rx_queue_N_packets shows the number of
-packets processed by the Nth queue.
-
-NOTE: Receive Packet Steering (RPS) and Receive Flow Steering (RFS) are not
-compatible with Flow Director. IF Flow Director is enabled, these will be
-disabled.
-
-The following three parameters impact Flow Director.
-
-FdirMode
---------
-Valid Range: 0-2 (0=off, 1=ATR, 2=Perfect filter mode)
-Default Value: 1
-
- Flow Director filtering modes.
-
-FdirPballoc
------------
-Valid Range: 0-2 (0=64k, 1=128k, 2=256k)
-Default Value: 0
-
- Flow Director allocated packet buffer size.
-
-AtrSampleRate
---------------
-Valid Range: 1-100
-Default Value: 20
-
- Software ATR Tx packet sample rate. For example, when set to 20, every 20th
- packet, looks to see if the packet will create a new flow.
-
-Node
-----
-Valid Range: 0-n
-Default Value: 1 (off)
-
- 0 - n: where n is the number of NUMA nodes (i.e. 0 - 3) currently online in
- your system
- 1: turns this option off
-
- The Node parameter will allow you to pick which NUMA node you want to have
- the adapter allocate memory on.
-
-max_vfs
--------
-Valid Range: 1-63
-Default Value: 0
-
- If the value is greater than 0 it will also force the VMDq parameter to be 1
- or more.
-
- This parameter adds support for SR-IOV. It causes the driver to spawn up to
- max_vfs worth of virtual function.
-
-
-Additional Configurations
-=========================
-
- Jumbo Frames
- ------------
- The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
- enabled by changing the MTU to a value larger than the default of 1500.
- The maximum value for the MTU is 16110. Use the ip command to
- increase the MTU size. For example:
-
- ip link set dev ethx mtu 9000
-
- The maximum MTU setting for Jumbo Frames is 9710. This value coincides
- with the maximum Jumbo Frames size of 9728.
-
- Generic Receive Offload, aka GRO
- --------------------------------
- The driver supports the in-kernel software implementation of GRO. GRO has
- shown that by coalescing Rx traffic into larger chunks of data, CPU
- utilization can be significantly reduced when under large Rx load. GRO is an
- evolution of the previously-used LRO interface. GRO is able to coalesce
- other protocols besides TCP. It's also safe to use with configurations that
- are problematic for LRO, namely bridging and iSCSI.
-
- Data Center Bridging, aka DCB
- -----------------------------
- DCB is a configuration Quality of Service implementation in hardware.
- It uses the VLAN priority tag (802.1p) to filter traffic. That means
- that there are 8 different priorities that traffic can be filtered into.
- It also enables priority flow control which can limit or eliminate the
- number of dropped packets during network stress. Bandwidth can be
- allocated to each of these priorities, which is enforced at the hardware
- level.
-
- To enable DCB support in ixgbe, you must enable the DCB netlink layer to
- allow the userspace tools (see below) to communicate with the driver.
- This can be found in the kernel configuration here:
-
- -> Networking support
- -> Networking options
- -> Data Center Bridging support
-
- Once this is selected, DCB support must be selected for ixgbe. This can
- be found here:
-
- -> Device Drivers
- -> Network device support (NETDEVICES [=y])
- -> Ethernet (10000 Mbit) (NETDEV_10000 [=y])
- -> Intel(R) 10GbE PCI Express adapters support
- -> Data Center Bridging (DCB) Support
-
- After these options are selected, you must rebuild your kernel and your
- modules.
-
- In order to use DCB, userspace tools must be downloaded and installed.
- The dcbd tools can be found at:
-
- http://e1000.sf.net
-
- Ethtool
- -------
- The driver utilizes the ethtool interface for driver configuration and
- diagnostics, as well as displaying statistical information. The latest
- ethtool version is required for this functionality.
-
- The latest release of ethtool can be found from
- https://www.kernel.org/pub/software/network/ethtool/
-
- FCoE
- ----
- This release of the ixgbe driver contains new code to enable users to use
- Fiber Channel over Ethernet (FCoE) and Data Center Bridging (DCB)
- functionality that is supported by the 82598-based hardware. This code has
- no default effect on the regular driver operation, and configuring DCB and
- FCoE is outside the scope of this driver README. Refer to
- http://www.open-fcoe.org/ for FCoE project information and contact
- e1000-eedc@lists.sourceforge.net for DCB information.
-
- MAC and VLAN anti-spoofing feature
- ----------------------------------
- When a malicious driver attempts to send a spoofed packet, it is dropped by
- the hardware and not transmitted. An interrupt is sent to the PF driver
- notifying it of the spoof attempt.
-
- When a spoofed packet is detected the PF driver will send the following
- message to the system log (displayed by the "dmesg" command):
-
- Spoof event(s) detected on VF (n)
-
- Where n=the VF that attempted to do the spoofing.
-

-Known Issues
-============
-
- Enabling SR-IOV in a 32-bit or 64-bit Microsoft* Windows* Server 2008/R2
- Guest OS using Intel (R) 82576-based GbE or Intel (R) 82599-based 10GbE
- controller under KVM
- ------------------------------------------------------------------------
- KVM Hypervisor/VMM supports direct assignment of a PCIe device to a VM. This
- includes traditional PCIe devices, as well as SR-IOV-capable devices using
- Intel 82576-based and 82599-based controllers.
-
- While direct assignment of a PCIe device or an SR-IOV Virtual Function (VF)
- to a Linux-based VM running 2.6.32 or later kernel works fine, there is a
- known issue with Microsoft Windows Server 2008 VM that results in a "yellow
- bang" error. This problem is within the KVM VMM itself, not the Intel driver,
- or the SR-IOV logic of the VMM, but rather that KVM emulates an older CPU
- model for the guests, and this older CPU model does not support MSI-X
- interrupts, which is a requirement for Intel SR-IOV.
-
- If you wish to use the Intel 82576 or 82599-based controllers in SR-IOV mode
- with KVM and a Microsoft Windows Server 2008 guest try the following
- workaround. The workaround is to tell KVM to emulate a different model of CPU
- when using qemu to create the KVM guest:
-
- "-cpu qemu64,model=13"

-- Congestion control
-- How the new TCP output machine [nyi] works
-
-Congestion control
-==================
-
-The following variables are used in the tcp_sock for congestion control:
-snd_cwnd The size of the congestion window
-snd_ssthresh Slow start threshold. We are in slow start if
- snd_cwnd is less than this.
-snd_cwnd_cnt A counter used to slow down the rate of increase
- once we exceed slow start threshold.
-snd_cwnd_clamp This is the maximum size that snd_cwnd can grow to.
-snd_cwnd_stamp Timestamp for when congestion window last validated.
-snd_cwnd_used Used as a highwater mark for how much of the
- congestion window is in use. It is used to adjust
- snd_cwnd down when the link is limited by the
- application rather than the network.
-
-As of 2.6.13, Linux supports pluggable congestion control algorithms.
-A congestion control mechanism can be registered through functions in
-tcp_cong.c. The functions used by the congestion control mechanism are
-registered via passing a tcp_congestion_ops struct to
-tcp_register_congestion_control. As a minimum, the congestion control
-mechanism must provide a valid name and must implement either ssthresh,
-cong_avoid and undo_cwnd hooks or the "omnipotent" cong_control hook.
-
-Private data for a congestion control mechanism is stored in tp->ca_priv.
-tcp_ca(tp) returns a pointer to this space. This is preallocated space - it
-is important to check the size of your private data will fit this space, or
-alternatively, space could be allocated elsewhere and a pointer to it could
-be stored here.
-
-There are three kinds of congestion control algorithms currently: The
-simplest ones are derived from TCP reno (highspeed, scalable) and just
-provide an alternative congestion window calculation. More complex
-ones like BIC try to look at other events to provide better
-heuristics. There are also round trip time based algorithms like
-Vegas and Westwood+.
-
-Good TCP congestion control is a complex problem because the algorithm
-needs to maintain fairness and performance. Please review current
-research and RFC's before developing new modules.
-
-The default congestion control mechanism is chosen based on the
-DEFAULT_TCP_CONG Kconfig parameter. If you really want a particular default
-value then you can set it using sysctl net.ipv4.tcp_congestion_control. The
-module will be autoloaded if needed and you will get the expected protocol. If
-you ask for an unknown congestion method, then the sysctl attempt will fail.
-
-If you remove a TCP congestion control module, then you will get the next
-available one. Since reno cannot be built as a module, and cannot be
-removed, it will always be available.
-
-How the new TCP output machine [nyi] works.
-===========================================
-
-Data is kept on a single queue. The skb->users flag tells us if the frame is
-one that has been queued already. To add a frame we throw it on the end. Ack
-walks down the list from the start.
-
-We keep a set of control flags
-
-
- sk->tcp_pend_event
-
- TCP_PEND_ACK Ack needed
- TCP_ACK_NOW Needed now
- TCP_WINDOW Window update check
- TCP_WINZERO Zero probing
-
-
- sk->transmit_queue The transmission frame begin
- sk->transmit_new First new frame pointer
- sk->transmit_end Where to add frames
-
- sk->tcp_last_tx_ack Last ack seen
- sk->tcp_dup_ack Dup ack count for fast retransmit
-
-
-Frames are queued for output by tcp_write. We do our best to send the frames
-off immediately if possible, but otherwise queue and compute the body
-checksum in the copy.
-
-When a write is done we try to clear any pending events and piggy back them.
-If the window is full we queue full sized frames. On the first timeout in
-zero window we split this.
-
-On a timer we walk the retransmit list to send any retransmits, update the
-backoff timers etc. A change of route table stamp causes a change of header
-and recompute. We add any new tcp level headers and refinish the checksum
-before sending.

+ * @hw: pointer to the hw struct

+ * This function enables/disables the FW logging via Rx CQ events and a UART
+ * port based on predetermined configurations. FW logging via the Rx CQ can be
+ * enabled/disabled for individual PF's. However, FW logging via the UART can
+ * only be enabled/disabled for all PFs on the same device.
+ *
+ * To enable overall FW logging, the "cq_en" and "uart_en" enable bits in
+ * hw->fw_log need to be set accordingly, e.g. based on user-provided input,
+ * before initializing the device.
+ *
+ * When re/configuring FW logging, callers need to update the "cfg" elements of
+ * the hw->fw_log.evnts array with the desired logging event configurations for
+ * modules of interest. When disabling FW logging completely, the callers can
+ * just pass false in the "enable" parameter. On completion, the function will
+ * update the "cur" element of the hw->fw_log.evnts array with the resulting
+ * logging event configurations of the modules that are being re/configured. FW
+ * logging modules that are not part of a reconfiguration operation retain their
+ * previous states.
+ *
+ * Before resetting the device, it is recommended that the driver disables FW
+ * logging before shutting down the control queue. When disabling FW logging
+ * ("enable" = false), the latest configurations of FW logging events stored in
+ * hw->fw_log.evnts[] are not overridden to allow them to be reconfigured after
+ * a device reset.
+ *
+ * When enabling FW logging to emit log messages via the Rx CQ during the
+ * device's initialization phase, a mechanism alternative to interrupt handlers
+ * needs to be used to extract FW log messages from the Rx CQ periodically and
+ * to prevent the Rx CQ from being full and stalling other types of control
+ * messages from FW to SW. Interrupts are typically disabled during the device's
+ * initialization phase.

+ * 2. Put the return address from the callee to the caller into
+ * register ret_reg().
+ * 3. (After defer slots are consumed) Jump to the subroutine that
+ * pushes the registers to the stack.
+ * The subroutine acts as a trampoline, and returns to the address in
+ * imm_b(), i.e. jumps to the callee.
+ *
+ * - If callee does not need to save R6~R9 then just load return
+ * address to the caller in ret_reg(), and jump to the callee
+ * directly.
+ *
+ * Using ret_reg() to pass the return address to the callee is set here
+ * as a convention. The callee can then push this address onto its
+ * stack frame in its prologue. The advantages of passing the return
+ * address through ret_reg(), instead of pushing it to the stack right
+ * here, are the following:
+ * - It looks cleaner.
+ * - If the called function is called multiple time, we get a lower
+ * program size.
+ * - We save two no-op instructions that should be added just before
+ * the emit_br() when stack depth is not null otherwise.
+ * - If we ever find a register to hold the return address during whole
+ * execution of the callee, we will not have to push the return
+ * address to the stack for leaf functions.

-* Add a DPAA2 MAC kernel driver in order to allow PHY management; currently
- the DPMAC objects and their link to DPNIs are handled by MC internally
- and all PHYs are seen as fixed-link
-* add more debug support: decide how to expose detailed debug statistics,
- add ingress error queue support
-* MC firmware uprev; the DPAA2 objects used by the Ethernet driver need to
- be kept in sync with binary interface changes in MC
-* refine README file
-* cleanup
-
-NOTE: None of the above is must-have before getting the DPAA2 Ethernet driver
-out of staging. The main requirement for that is to have the drivers it
-depends on, fsl-mc bus and DPIO driver, moved to drivers/bus and drivers/soc
-respectively.

+NET COMMANDS
+============
+
+| **bpftool** **net { show | list } [ dev name ]**
+| **bpftool** **net help**
+
+DESCRIPTION
+===========
+ **bpftool net { show | list } [ dev name ]**
+ List bpf program attachments in the kernel networking subsystem.
+
+ Currently, only device driver xdp attachments and tc filter
+ classification/action attachments are implemented, i.e., for
+ program types **BPF_PROG_TYPE_SCHED_CLS**,
+ **BPF_PROG_TYPE_SCHED_ACT** and **BPF_PROG_TYPE_XDP**.
+ For programs attached to a particular cgroup, e.g.,
+ **BPF_PROG_TYPE_CGROUP_SKB**, **BPF_PROG_TYPE_CGROUP_SOCK**,
+ **BPF_PROG_TYPE_SOCK_OPS** and **BPF_PROG_TYPE_CGROUP_SOCK_ADDR**,
+ users can use **bpftool cgroup** to dump cgroup attachments.
+ For sk_{filter, skb, msg, reuseport} and lwt/seg6
+ bpf programs, users should consult other tools, e.g., iproute2.
+
+ The current output will start with all xdp program attachments, followed by
+ all tc class/qdisc bpf program attachments. Both xdp programs and
+ tc programs are ordered based on ifindex number. If multiple bpf
+ programs attached to the same networking device through **tc filter**,
+ the order will be first all bpf programs attached to tc classes, then
+ all bpf programs attached to non clsact qdiscs, and finally all
+ bpf programs attached to root and clsact qdisc.
+
+ **bpftool net help**
+ Print short help message.
+
+OPTIONS
+=======
+ -h, --help
+ Print short generic help message (similar to **bpftool help**).
+
+ -v, --version
+ Print version number (similar to **bpftool version**).
+
+ -j, --json
+ Generate JSON output. For commands that cannot produce JSON, this
+ option has no effect.
+
+ -p, --pretty
+ Generate human-readable JSON output. Implies **-j**.

+# A test for switch behavior under MC overload. An issue in Spectrum chips
+# causes throughput of UC traffic to drop severely when a switch is under heavy
+# MC load. This issue can be overcome by putting the switch to MC-aware mode.
+# This test verifies that UC performance stays intact even as the switch is
+# under MC flood, and therefore that the MC-aware mode is enabled and correctly
+# configured.
+#
+# Because mlxsw throttles CPU port, the traffic can't actually reach userspace
+# at full speed. That makes it impossible to use iperf3 to simply measure the
+# throughput, because many packets (that reach $h3) don't get to the kernel at
+# all even in UDP mode (the situation is even worse in TCP mode, where one can't
+# hope to see more than a couple Mbps).
+#
+# So instead we send traffic with mausezahn and use RX ethtool counters at $h3.
+# Multicast traffic is untagged, unicast traffic is tagged with PCP 1. Therefore
+# each gets a different priority and we can use per-prio ethtool counters to
+# measure the throughput. In order to avoid prioritizing unicast traffic, prio
+# qdisc is installed on $swp3 and maps all priorities to the same band #7 (and
+# thus TC 0).
+#
+# Mausezahn can't actually saturate the links unless it's using large frames.
+# Thus we set MTU to 10K on all involved interfaces. Then both unicast and
+# multicast traffic uses 8K frames.
