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. Signed-off-by: David S. Miller <[email protected]>
