// Module interface for IGMP modules.
// An IGMP module sends notifications about multicast group memberships in hosts,
// and processes these notifications in multicast routers.
// Currently there are 3 versions specified in RFC 1112 (IGMPv1), RFC 2236 (IGMPv2),
// and RFC 3376 (IGMPv3).
// IGMP packets are transported by the IP layer connected to the ipIn/ipOut
// gates. Some multicast routing protocols (e.g. DVMRP) also communitacate with
// IGMP messages. They must be connected to the routerIn/routerOut gates,
// the IGMP module will pass up the unrecognized IGMP packets.
// @see ~Igmpv2
