I have 2 questions:
1) if you change the opcode to RDMA Write, do you still experience this

(assuming that the permissions allow RDMA Write; if not, fix this issue)

Yes, that fixes the return value but nothing (at least currently)
takes advantage of that. Is that the next step ?

Hi Slava,
This patch is outdated (it was outdated at date of posting to the list),
in particular I cleaned up already a needs to resolve multicast group by

others.

This consolidation makes a code cleaner and will help us to add MGID to
MLID compression model where mgrp will not be mapped directly to mlids
but using additional structure.

Now each MLID value is represented by collection of multicast groups

mckey is intended to be a fairly simple send/receive multicast test program.
What's the reasoning behind adding the event handling?
