====================
10GbE Intel Wired LAN Driver Updates 2016-08-20

This series contains updates to ixgbe and ixgbevf.

Veola fixes how the backplane reports the media in ethtool, as KR, KX or
KX4 based on the backplane interface present.

Emil fixes ixgbevf since an incorrect size parameter for
ixgbevf_write_msg_read_ack() ended up only giving the PF the first 4
bytes of the MAC address, so correct the size by calculating it on the
fly for all instances where we call ixgbevf_write_msg_read_ack().  Added
geneve receive offload support for x550em_a.

Don fixes the LED interface for x557 since it uses a different interface.
Added support for the new x557 copper device.
