Processing multicast / broadcast in fast path is performance draining and having more links means more cloning and bringing performance down further. Broadcast; in particular, need to be given to all the virtual links. Earlier tricks of enabling broadcast bit for IPv4 only interfaces are not really working since it fails autoconf. Which means enabling broadcast for all the links if protocol specific hacks do not have to be added into the driver. This patch defers all (incoming as well as outgoing) multicast traffic to a work-queue leaving only the unicast traffic in the fast-path. Now if we need to apply any additional tricks to further reduce the impact of this (multicast / broadcast) type of traffic, it can be implemented while processing this work without affecting the fast-path.
