There are four 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. Changes from V1: 1. add define to sendonly_full_member join state, instead of "8" 2. change commit message to introduce the capmask2 3. number name instead of digit in commit message 4. SA agent instead of SA in commit message header. Changes from V2: 1. returned back to one field in ib_class_port_info (as in V0).
