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 2017-04-29

This series contains updates to ixgbe and ixgbevf only, most notable is
the addition of XDP support to our 10GbE drivers.

Paul fixes ixgbe to acquire the PHY semaphore before accessing PHY
registers when issuing a device reset.

John adds XDP support (yeah!) for ixgbe.

Emil fixes an issue by flushing the MACVLAN filters on VF reset to avoid
conflicts with other VFs that may end up using the same MAC address.  Also
fixed a bug where ethtool -S displayed some empty fields for ixgbevf
because it was using ixgbe_stats instead ixgbevf_stats for
IXGBEVF_QUEUE_STATS_LEN.

Tony adds the ability to specify a zero MAC address in order to clear the
VF's MAC address from the RAR table.  Also adds support for a new
1000Base-T device based on x550EM_X MAC type.  Fixed an issue where the
RSS key specified by the user would be over-written with a pre-existing
value, so change the rss_key to a pointer so we can check to see if the
key has a value set before attempting to set it.  Fixed the logic for
mailbox support for getting RETA and RSS values, which are only supported
by 82599 and x540 devices.

v2: fixed up patches #2 and #3 based on feedback from Jakub and to
    address build issues when page sizes are larger than 4k
