Sean,

Can you explain how this relates to your multicast changes? the IPoIB 
send-only-full-member-join hack was there before your patch and stayed 
there after your patch... and how come a change in the multicast code 
can cause the error steam to be finite... have you moved the retry 
mechanism from the ib_sa consumer to the ib_sa mcast engine?

Or.
