Let me see that i follow: rdma_established is to be used by app which
is a CMA consumer and now polls from a CQ a completion associated with
a QP whose state is RTR (ie no RTU == ESTABLISHED event) was received
yet. This may solve the need of apps who do not want to wait for the
synthesized ESTABLISHED event that would be delivered at some future
point with the approach taken by your patch.

Moreover, the solution is one of:
 - the patch you sent
- enforcing the ULP to call rdma_establish (or cm_establish for direct
CM consumers) else a repeatedly lost RTU case is not handled.

what do you mean by event forwarding, is it to fwd the COMM_EST event
from the app QP handler to the CM/CMA?

Or.
