Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

In netdevice.h we removed the structure in net-next that is being
changes in 'net'.  In macsec.c and rtnetlink.c we have overlaps
between fixes in 'net' and the u64 attribute changes in 'net-next'.

The mlx5 conflicts have to do with vxlan support dependencies.

 LCO is a technique for efficiently computing the outer checksum of an
