The set looks good to me, the bridge and vlan direct dependency is gone and

IDK, vlan knows it's calling the bridge:

going thru the generic NETDEV notifier seems odd.

If this is just to avoid the dependency we can perhaps add a stub 
like net/ipv4/udp_tunnel_stub.c ?

If the others are ok with it I think you can send it as non-RFC, but I'd give it
a few more days at least. :)
