Merge branch 'net-improve-vxlan-option-process-in-net_sched-and-lwtunnel'

====================
net: improve vxlan option process in net_sched and lwtunnel
This patch is to do some mask when setting vxlan option in net_sched
and lwtunnel, so that only available bits can be set on vxlan md gbp.
This would help when users don't know exactly vxlan's gbp bits, and
avoid some mismatch because of some unavailable bits set by users.
