Tom,

FWIW, note that the netlink code which relates to vxlan netdevice
creation through rtnl link ops itself doesn't come
into play for the openvswitch vxlan use case, the shared section
between OVS vxlan ports and the rtnl link ops one
vxlan_sock_add() - so you might choose to propagate  the new values
through the ovs channel as a use case.

Or.
