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.
