Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next...

Jeff Kirsher says:

====================
1GbE Intel Wired LAN Driver Updates 2016-08-18

This series contains updates to igb only.

Gangfeng Huang provides all the changes in the series to update the
igb driver to support advanced receive side filters that direct receive
packets by flows to different hardware queues. This enables a tight
control on routing a flow in the platform.  First patch allows for
receive network flow classification to insert and remove receive filters
by ethtool.  Second and third patches add the ability to insert and
remove ethertype and VLAN priority filters by ethtool.

Last patch just fixes an error message to return "Not supported" versus
"Unknown error 524".
