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

Jeff Kirsher says:

====================
This series contains updates to ixgbevf and e1000e.

Alex's ixgbevf patch is meant to address several race issues that become
possible because next_to_watch could possibly be set to a value that shows
that the descriptor is done when it is not.  In order to correct that we
instead make next_to_watch a pointer that is set to NULL during cleanup,
and set to the eop_desc after the descriptor rings have been written.

Stephen's ixgbevf patch makes the PCI id table a const and reformats the
table to match what the ixgbe driver does.

The remaining 13 patches from Bruce are cleanup patches for e1000e to
resolve checkpatch.pl warnings/errors, removing blank lines where
necessary and fix code formatting.
