I agree with Andy. We still keep one reinject (netif_rx), which is probably better that two
(__netif_receive_skb), but not enough.
I really think we need a general framework for late delivery of final packets to packet handler
registered somewhere in the rx_handler path.
Jiri, is this patch the one you announced as "I have some kind nice solution in mind and I'm going
to submit that as a patch later (too many patches are in the wind atm)" ?
