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.
