From d19742fb1c68e6db83b76e06dea5a374c99e104f Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 20 Oct 2009 01:06:22 -0700 Subject: 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 Signed-off-by: David S.
