It should be able to work just as it does for userspace.  The user either calls 
accept or reject.  The IB CM will not send an RTU if a REJ has been sent.

I think that the real issue here is that the CMA determines whether to hand the 
REP to the user based on if it has a QP.  This was done to support userspace. 
SDP wants the CMA to manage its QP, but still wants to see the REP.  What I need 
to determine is if it's easier/better for SDP to manage the QP itself, or to 
change the CMA to expose the REP when it manages the QP states.
