  Hash : be383d54
  Message : Call igmp_sendpkt() and mld6_sendpkt() with pktinfo argument. Gather all information needed to send an IGMP or MLD6 packet in a struct pktinfo. This allows splitting access to multicast data structures from sending packets. Then adding locks to multicast will be easier. OK mvs@
