Currently, in igb_resume(), igb driver ignores the Wake Up Status (WUS)
and Wake Up Packet Memory (WUPM) registers. This patch enables the igb
driver to read the WUPM if the controller was woken by a wake up packet
that is not more than 128 bytes long (maximum WUPM size), then pass it
up the kernel network stack.

Add functionality for the VF to request up to 3 additional MAC filters.
This is done using existing E1000_VF_SET_MAC_ADDR message, but with
additional message info - E1000_VF_MAC_FILTER_CLR to clear all unicast
MAC filters previously set for this VF and E1000_VF_MAC_FILTER_ADD to
add MAC filter.
Additional filters can be added only in case if administrator did not
set VF MAC explicitly and allowed to change default MAC to the VF.
Due to the limited number of RAR entries reserve at least 3 MAC filters
for the PF.
If SRIOV is supported by the NIC after this change RAR entries starting
from 1 to (RAR MAX ENTRIES - NUM SRIOV VFS) will be used for PF and VF
MAC filters.

After an upgrade to Linux kernel v4.x the hardware timestamps of the
82579 Gigabit Ethernet Controller are different than expected.
The values that are being read are almost four times as big as before
the kernel upgrade.
The difference is that after the upgrade the driver sets the clock
frequency to 25MHz, where before the upgrade it was set to 96MHz. Intel
confirmed that the correct frequency for this network adapter is 96MHz.

10GbE Intel Wired LAN Driver Updates 2017-04-18
This series contains updates to mainly ixgbe with only one ixgbevf change.
Usha adds a check to ensure the creation of number of VF's is valid based
on the traffic classes configured, all to avoid transmit hangs.
Joe Perches reduces the use of pr_cont since the output can be interleaved
by other processes.
Tony cleans up the code overwriting the KX4 config, which is configured by
the NVM. Adds a check for MMNGC.MNG_VETO, to resolve an issue where we
were getting a link loss for the BMC when loading the driver.
Don fixes up SGMII x553 config details which were missed in earlier
implementations. Added support for x552 XFI backplane interface support.
Cleaned up an unused define, which was causing confusion on supported
devices.
Emil fixes a link issue on KR parts by making sure the default setting is
set. Refactors the code so that the code for allocating memory for the
list of MAC addresses that the VFs can use into its own function. Made
some code cleans to help readability and ensure notification of SRIOV
being enabled is done upon completion. Fixed an issue where if we failed
to allocate vfinfo in __ixgbe_enable_sriov() the driver would crash with
a NULL pointer dereference.
Philippe Reynes updates ixgbevf to use the new API for
{get|set}_link_ksettings.
Alex increases the headroom allocation when using build_skb() on a
system with 4K pages. Fixed an issue in ixgbe_dump() where we were no
longer clearing the status bit.

tcp: address two poll() flakes

When using TCP FastOpen for an active session, we send one wakeup event
from tcp_finish_connect(), right before the data eventually contained in
the received SYNACK is queued to sk->sk_receive_queue.
This means that depending on machine load or luck, poll() users
might receive POLLOUT events instead of POLLIN|POLLOUT
To fix this, we need to move the call to sk->sk_state_change()
after the (optional) call to tcp_rcv_fastopen_synack()

When a RST packet is processed, we send two wakeup events to interested
polling users.
First one by a sk->sk_error_report(sk) from tcp_reset(),
followed by a sk->sk_state_change(sk) from tcp_done().
Depending on machine load and luck, poll() can either return POLLERR,
or POLLIN|POLLOUT|POLLERR|POLLHUP (this happens on 99 % of the cases)
This is probably fine, but we can avoid the confusion by reordering
things so that we have more TCP fields updated before the first wakeup.
This might even allow us to remove some barriers we added in the past.

mlxsw: Allow flow based forwarding in OVS
This patchset does some fixes so the HW is setup correctly to do
flow-based (ACL based) forwarding for OVS-enslaved port.
The first patch is just trivial fix spotted on the way.
Patches 2-4 take care of proper FID setup which HW needs in order to
for ACL based forwarding.
The 7th patch (with dependency of patch 5 and 6) takes care of proper setup
of ports that are enslaved in OVS.
The last patch implements new FID miss trap that is used to push

When there is no FID set for a specific packet, the HW will drop it.
However, by default these packets are useful to be delivered to CPU as
it can inspect them and program HW accordingly. So add this trap.
This would only ever happen when port is enslaved to an OVS master.
Otherwise, packets would be dropped during VLAN / STP filtering,
before FID classification.

net: dsa: add SMSC/Microchip LAN9303 three port ethernet switch driver
The LAN9303 is a three port 10/100 ethernet switch with integrated phys
for the two external ethernet ports. The third port is an RMII/MII
interface to a host master network interface (e.g. fixed link).
While the LAN9303 device itself supports offload packet processing, this
driver does not make use of it yet. This driver just configures the device
to provide two separate network interfaces (which is the default state of
a DSA device).
Please note: the "MDIO managed mode" driver part isn't tested yet. I have
used and tested the "I2C managed mode" only.
Changes in v6:
- fix support to use the driver as a module (core, i2c and mdio)
- license info added in all parts of the driver (for module support)
Changes in v5:
- add missing include file to 'net/dsa/tag_lan9303.c'
Changes in v4:
- rebased on net-next, 'net/dsa/tag_lan9303.c' adapted to changed API
Changes in v3:
- 'ds_to_lan9303()' removed
- special PHY reg MII_LAN911X_SPECIAL_CONTROL_STATUS mapping removed
- compatible strings for I2C and MDIO are now different
- MDIO-managed-mode devicetree binding added (still compile time tested only)
Changes in v2:
- code moved to 'drivers/net/dsa'
- timeouts in completion wait loops
- macros instead of various magic numbers
- development code removed
- devicetree property names changed
- devicetree example adapted
- tried to avoid to mix 'switching' and 'forwarding'...
Comments are welcome.

To define the outgoing port and to discover the incoming port a regular

This tag handler/filter depends on some hardware features which must be
enabled in the device to provide and make use of this special VLAN tag
to control the destination and the source of an ethernet packet.

This patch increases the headroom allocated when using build_skb on a
system with 4K pages. Specifically the breakdown of headroom versus cache
size is as follows:
L1 Cache Size Headroom
64 192
64, NET_IP_ALIGN == 2 194
128 128
128, NET_IP_ALIGN == 2 130
256 512
256, NET_IP_ALIGN == 2 258
I stopped at supporting only a cache line size of 256 as that was the
largest cache size I could find supported in the kernel.
With this we are guaranteeing at least 128 bytes of headroom to spare in
the frame. This should be enough for us to insert a couple of IPv6 headers
if needed which is likely enough room for anything XDP should need.
I'm leaving the padding for systems with pages larger than 4K unmodified
for now. XDP currently isn't really setup to work on those types of
systems so we can cross that bridge when we get there.

This fixes an issue where if we failed to allocate vfinfo in

ixgbe_disable_sriov() when attempting to free the vfinfo struct based

kernel text, data, and bss fit in the required 32MB limit, but this
option is not set for every config that enables lockdep.
A 4.10 kernel fails to boot with the console output
Kernel: Using 8 locked TLB entries for main kernel image.
hypervisor_tlb_lock[2000000:0:8000000071c007c3:1]: errors with f
Program terminated
with these config options
CONFIG_LOCKDEP=y
CONFIG_LOCK_STAT=y
CONFIG_PROVE_LOCKING=n
To fix, rename CONFIG_PROVE_LOCKING_SMALL to CONFIG_LOCKDEP_SMALL, and
enable this option with CONFIG_LOCKDEP=y so we get the reduced memory
usage every time lockdep is turned on.
Tested that CONFIG_LOCKDEP_SMALL is set to 'y' if and only if
CONFIG_LOCKDEP is set to 'y'. When other lockdep-related config options
that select CONFIG_LOCKDEP are enabled (e.g. CONFIG_LOCK_STAT or
CONFIG_PROVE_LOCKING), verified that CONFIG_LOCKDEP_SMALL is also
enabled.
Fixes: e6b5f1be7afe ("config: Adding the new config parameter CONFIG_PROVE_LOCKING_SMALL for sparc")

We forgot to indicate some of the supported speed on the X553
backplane. This patch attempts to correct for that.
