filter: Add SKF_AD_QUEUE instruction
It can help being able to filter packets on their queue_mapping. If filter performance is not good, we could add a "numqueue" field in struct packet_type, so that netif_nit_deliver() and other functions can directly ignore packets with not expected queue number. Lets experiment this simple filter extension first. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
