Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/gi…

…t/jkirsher/net-next

Jeff Kirsher says:

====================
This series contains updates to ixgbe, ixgbevf, igbvf, igb and
networking core (bridge).  Most notably is the addition of support
for local link multicast addresses in SR-IOV mode to the networking
core.

Also note, the ixgbe patch "ixgbe: Add support for pipeline reset" and
"ixgbe: Fix return value from macvlan filter function" is revised based
on community feedback.
====================
