2016-04-06net: intel: remove dead linksJiri Benc1-66/+14
The Kconfig for Intel NICs references two different URLs for the "Adapter & Driver ID Guide". Neither of those two links works. The current URL seems to be http://www.intel.com/content/www/us/en/support/network-and-i-o/ethernet-products/000005584.html but given it's apparently constantly changing, there's no point in having it in the help text. Just keep a generic pointer to http://support.intel.com. Hopefully, this one will have a longer live. It still works, at least. Furthermore, remove a link to "the latest Intel PRO/100 network driver for Linux", this has no place in the mainline kernel and the latest Linux driver it offers is from 2006, anyway.

2016-04-06mlxsw: spectrum: Add IEEE 802.1Qbb PFC supportIdo Schimmel4-11/+158
Implement the appropriate DCB ops and allow a user to configure certain traffic classes as lossless. The operation configures PFC for both the egress (respecting PFC frames) and ingress (sending PFC frames) parts of the port. At egress, when a PFC frame is received for a PFC enabled priority, then all the priorities mapped to the same TC are stopped. At ingress, the priority group (PG) buffers to which the enabled PFC priorities are mapped are configured to be lossless. PFC frames will be transmitted when the Xoff threshold is crossed. The user-supplied delay parameter is used to determine the PG's size according to the following formula: PG_SIZE = PG_SIZE_LOSSY + delay * CELL_FACTOR + MTU In the worst case scenario the delay will be made up of packets that are all of size CELL_SIZE + 1, which means each packet will require almost twice its true size when buffered in the switch. We therefore multiply this value by the "cell factor", which is close to 2. Another MTU is added in case the transmitting host already started transmitting a maximum length frame when the PFC packet was received. As with PAUSE enabled ports, when the port's MTU is changed both the PGs' size and threshold are adjusted accordingly.

2016-04-06mlxsw: spectrum: Add support for PAUSE framesIdo Schimmel3-10/+95
When a packet ingress the switch it's placed in its assigned priority group (PG) buffer in the port's headroom buffer while it goes through the switch's pipeline. After going through the pipeline - which determines its egress port(s) and traffic class - it's moved to the switch's shared buffer awaiting transmission. However, some packets are not eligible to enter the shared buffer due to exceeded quotas or insufficient space. Marking their associated PGs as lossless will cause the packets to accumulate in the PG buffer. Another reason for packets accumulation are complicated pipelines (e.g. involving a lot of ACLs). To prevent packets from being dropped a user can enable PAUSE frames on the port. This will mark all the active PGs as lossless and set their size according to the maximum delay, as it's not configured by user. +----------------+ + | | | | | | | | | | | | | | | | | | Delay | | | | | | | | | | | | | | | Xon/Xoff threshold +----------------+ + | | | | | | 2 * MTU | | | +----------------+ + The delay (612 [Cells]) was calculated according to worst-case scenario involving maximum MTU and 100m cables. After marking the PGs as lossless the device is configured to respect incoming PAUSE frames (Rx PAUSE) and generate PAUSE frames (Tx PAUSE) according to user's settings. Whenever the port's headroom configuration changes we take into account the PAUSE configuration, so that we correctly set the PG's type (lossy / lossless), size and threshold. This can happen when: a) The port's MTU changes, as it directly affects the PG's size. b) A PG is created following user configuration, by binding a priority to it. Note that the relevant SUPPORTED flags were already mistakenly set by the driver before this commit.

2016-04-06mlxsw: spectrum: Initialize egress schedulingIdo Schimmel1-0/+111
Before introducing support for DCB ops we should first make sure we initialize the relevant parts in the device correctly. Specifically, the egress scheduling. The device supports a superset of the 802.1Qaz standard with 4 hierarchy levels that can be linked to each other in multiple ways and with different transmission selection algorithms (TSA) employed between them. However, since we only intend to support the 802.1Qaz standard we flatten the hierarchies and let the user configure via DCB ops the TSA and max rate shaper at the subgroup hierarchy (see figure below) and the mapping between switch priority to traffic class. By default, all switch priorities are mapped to traffic class 0, strict priority is employed and max shaper is disabled.

2016-04-06mlxsw: spectrum: Correctly configure headroom sizeIdo Schimmel2-10/+34
When packets ingress the switch they are assigned a switch priority and directed to the corresponding priority group (PG) buffer in the port's headroom buffer. Since we now map all switch priorities to priority group 0 (PG0) by default, there is no need to allocate the other priority groups during initialization. The only exception is PG9, which is used for control traffic. At minimum, the PG should be able to store the currently classified packet (pipeline latency isn't 0) and also the packets arriving during the classification time. However, an incoming packet will not be buffered if there is no available MTU-sized buffer space for storing it. The buffer needed to accommodate for pipeline latency is variable and needs to take into account both the current link speed and current latency of the pipeline, which is time-dependent. Testing showed that setting the PG's size to twice the current MTU is optimal. Since PG9 is used strictly for control packets and not subject to flow control, we are not going to resize it according to user configuration, so we simply set it according to worst case scenario, which is twice the maximum MTU. In any case, later patches in the series will allow a user to direct lossless flows to other PGs than PG0 and set their size to accommodate for round-trip propagation delay. The above change also requires us to resize the PG buffer whenever the port's MTU is changed.

2016-04-06mlxsw: spectrum: Map all switch priorities to priority group 0Ido Schimmel1-1/+24
During transmission, the skb's priority is used to map the skb to a traffic class, where the idea is to group priorities with similar characteristics (e.g. lossy, lossless) to the same traffic class. By default, all priorities are mapped to traffic class 0. In the device, we model the skb's priority as the switch priority, which is assigned to a packet according to its PCP value and ingress port (untagged packets are assigned the port's default switch priority - 0). At ingress, the packet is directed to a priority group (PG) buffer in the port's headroom buffer according to the packet's switch priority and switch priority to buffer mapping. While it's possible to configure the egress mapping between skb's priority (switch priority) and traffic class, there is no mechanism to configure the ingress mapping to a PG. In order to keep things simple and since grouping certain priorities into a traffic class at egress also implies they should be grouped the same at ingress, treat a PG as the ingress counterpart of an egress traffic class. Having established the above, during initialization map all the switch priorities to PG0 in accordance with the Linux defaults for traffic class mapping.

2016-04-06vxlan: implement GPEJiri Benc3-17/+222
Implement VXLAN-GPE. Only COLLECT_METADATA is supported for now (it is possible to support static configuration, too, if there is demand for it). The GPE header parsing has to be moved before iptunnel_pull_header, as we need to know the protocol. v2: Removed what was called "L2 mode" in v1 of the patchset. Only "L3 mode" (now called "raw mode") is added by this patch. This mode does not allow Ethernet header to be encapsulated in VXLAN-GPE when using ip route to specify the encapsulation, IP header is encapsulated instead. The patch does support Ethernet to be encapsulated, though, using ETH_P_TEB in skb->protocol. This will be utilized by other COLLECT_METADATA users (openvswitch in particular). If there is ever demand for Ethernet encapsulation with VXLAN-GPE using ip route, it's easy to add a new flag switching the interface to "Ethernet mode" (called "L2 mode" in v1 of this patchset). For now, leave this out, it seems we don't need it. Disallowed more flag combinations, especially RCO with GPE. Added comment explaining that GBP and GPE cannot be set together.

2016-04-06igb: allow setting MAC address on i211 using a device tree blobJohn Holland1-3/+6
The Intel i211 LOM PCIe Ethernet controllers' iNVM operates as an OTP and has no external EEPROM interface [1]. The following allows the driver to pickup the MAC address from a device tree blob when CONFIG_OF has been enabled.

2016-04-06igb: Add support for bulk Tx cleanup & cleanup boolean logicAlexander Duyck1-5/+7
This patch enables bulk free in Tx cleanup for igb and cleans up the boolean logic in the polling routines for igb in the hopes of avoiding any mix-ups similar to what occurred with i40e and i40evf.

2016-04-06igb: Fix sparse warning about passing __beXX into leXX_to_cpupAlexander Duyck1-4/+6
We were casting the addr as __beXX and then passing it into le32_to_cpu because the device expects the MAC address to be in network order even though the register set is little endian. Instead of casting it as __beXX we can just cast it as __leXX in order to maintain consistency since the region of memory is already in little endian order as far as we are concerned.

2016-04-05i40e/i40evf: Fix TSO checksum pseudo-header adjustmentAlexander Duyck2-14/+8
With IPv4 and IPv6 now using the same format for checksums based on the length of the frame we need to update the i40e and i40evf drivers so that they correctly account for lengths greater than or equal to 64K. With this patch the driver should now correctly update checksums for frames up to 16776960 in length which should be more than large enough for all possible TSO frames in the near future.

2016-04-05i40e: Request PHY media event at reset timeShannon Nelson1-0/+2
Add the Media Not Available flag to the link event mask. It seems that event comes first if you have a DA cable pulled out, but there's no follow-up event for Link Down; if you're not looking for MEDIA_NA you will get no event, even though there's now no Link.

2016-04-05i40e: Lower some message levelsMitch Williams1-5/+5
These conditions can happen any time VFs are enabled or disabled and are not really indicative of fatal problems unless they happen continuously. Lower the log level so that people don't get scared.
