Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next 

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates

This series contains updates to i40e and i40evf.

Most notable are:
Joseph completes the implementation of the ethtool ntuple rule
management interface by adding the get, update and delete interface
reset.

Akeem provides a fix to prevent a possible overflow due to multiplication
of number and size by using kzalloc, so use kcalloc.

Jesse provides an implementation for skb_set_hash() and adds the L4 type
return when we know it is an L4 hash.  He also adds a counter to
statistics for Tx timeouts to help users.  Lastly he provides a change
to stay away from the cache line where the done bit may be getting
written back for the transmit ring since the hardware may be writing the
whole cache line for a partial update.

Shannon cleans up code comments.

Anjali removes a firmware workaround for newer firmware since the number
of MSIx vectors are being reported correctly.

v2:
 -  dropped patch 01 of the series based on feedback from the author
    Joe Perches and Shannon Nelson.
