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) |
