__netif_receive_skb_core() does a depressingly large amount of per-packet work that can't easily be listified, because the another_round looping makes it nontrivial to slice up into smaller functions. Fortunately, most of that work disappears in the fast path: * Hardware devices generally don't have an rx_handler * Unless you're tcpdumping or something, there is usually only one ptype * VLAN processing comes before the protocol ptype lookup, so doesn't force a pt_prev deliver so normally, __netif_receive_skb_core() will run straight through and pass back the one ptype found in ptype_base[hash of skb->protocol].
