BTW, how does the VLAN TX acceleration work at all? It's using
skb->cb to carry the tags but then calls dev_queue_xmit. Once
you do that packet schedulers can scribble all over skb->cb.
Also vlan_skb_recv should be moved out-of-line. It's absolutely
humongous. It'll generate tail-calls anyway so performance-wise
it's useless.
I have a number of VLAN cleanups queued and intend to do these
two changes on top.
