IB/core: Support for CMA multicast join flags
Added UCMA and CMA support for multicast join flags. Flags are
passed using UCMA CM join command previously reserved fields.
Currently supporting two join flags indicating two different
multicast JoinStates:
1. Full Member:
The initiator creates the Multicast group(MCG) if it wasn't
previously created, can send Multicast messages to the group
and receive messages from the MCG.
2. Send Only Full Member:
The initiator creates the Multicast group(MCG) if it wasn't
previously created, can send Multicast messages to the group
but doesn't receive any messages from the MCG.
IB: Send Only Full Member requires a query of ClassPortInfo
to determine if SM/SA supports this option. If SM/SA
doesn't support Send-Only there will be no join request
sent and an error will be returned.
ETH: When Send Only Full Member is requested no IGMP join
will be sent.
