Merge branch '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue

Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2018-01-09

This series contains updates to ixgbe and ixgbevf only.

Emil fixes an issue with "wake on LAN"(WoL) where we need to ensure we
enable the reception of multicast packets so that WoL works for IPv6
magic packets.  Cleaned up code no longer needed with the update to
adaptive ITR.

Paul update the driver to advertise the highest capable link speed
when a module gets inserted.  Also extended the displaying of firmware
version to include the iSCSI and OEM block in the EEPROM to better
identify firmware versions/images.

Tonghao Zhang cleans up a code comment that no longer applies since
InterruptThrottleRate has been removed from the driver.

Alex fixes SR-IOV and MACVLAN offload interaction, where the MACVLAN
offload was incorrectly configuring several filters with the wrong
pool value which resulted in MACLVAN interfaces not being able to
receive traffic that had to pass over the physical interface.  Fixed
transmit hangs and dropped receive frames when the number of VFs
changed.  Added support for RSS on MACVLAN pools for X550 devices.
Fixed up the MACVLAN limitations so we can now support 63 offloaded
devices.  Cleaned up MACVLAN code that is no longer needed with the
recent changes and fixes.
