I would like to see at least one ACK from the netfilter
folks.  Bart or Rusty, could you forward to patch to
netfilter-devel for review?

I have some other ideas about how bridging might be able
to save some call chain depth... but I need to think about
it some more before proposing or even trying to implement.
(basically something akin to how we do route level packet
 output, via dst_output(), but instead we're doing this
 at ->hard_start_xmit() time)
