In vlan_skb_recv, packets are generally stripped of their vlan header,

performance penalty.
Its done to save stack space. There's currently a discussion
about making loopback use netif_receive_skb in case enough
stack is still available. Once that patch gets merged I'll
change VLAN in a similar way.
There was a patch floating around fixing VLAN + Bridge, I'm wondering if
it got any traction (ie merged), or if this would affect future merge of
that feature?
Whats broken with VLAN + Bridge? Do you have a pointer to
this patch?
