There are 4 types of multicast join: FullMember, NonMember, SendOnlyNonMember and SendOnlyFullMember. This patch-set introduces the ability to send multicast join requests of type SendOnlyFullMember (until now only the first three types were supported). Host that sends such join request, does not require a multicast subscription and will still send properly, and in addition will not get other multicast packets from that group. It adds a new SA query (for classport_info) to check that the sm supports sending such requests and it modifies multicast processing in the IB/core module to handle SendOnlyFullMember multicast join requests. In addition, the patch set modifies IPoIB so that if the sm does support SendOnlyFullMember join requests, IPoIB will send such a request when joining a sendonly multicast group. Changes from V0: PORTCLASSINFO_REC_FIELD changed to CLASSPORTINFO_REC_FIELD 2 fields in ib_class_port_info instead of one "sa" changed to SA "sa" in the headline changed to SA agent No need to indicates NUM_JOIN_MEMBERSHIP_TYPES = 4 Change the place the ipoib driver calls the new sa_query, does it once after the broadcast is joined.
