IPoIB: Set pkt_type correctly for multicast packets (fix IGMP breakage) IGMP processing is broken because the IPOIB does not set the skb->pkt_type the right way for multicast traffic. All incoming packets are set to PACKET_HOST which means that igmp_recv() will ignore the IGMP broadcasts/multicasts. This in turn means that the IGMP timers are firing and are sending information about multicast subscriptions unnecessarily. In a large private network this can cause traffic spikes.
