[openib-general] affiliated asynchronous errors

[keshetti mahesh]

suppose an work request is in process and due to some reason catastrophic error  occured then i assume that  the driver will report this error as an affiliated asynchronous error(IB_EVENT_QP_FATAL) to that QP
and there will not be any completion  corresponding to that work request(will there be ?????)
(am i right or missing something)

now as there is no event handler for the QP (suppose in the case of SDP )  how do the ULP come to know about it

Outstanding work requests should complete with flushed status.

I guess that SDP could detect an error when it polls the CQ and sees a 
non-success completion status.
