[ofa-general] error with ibv_poll_cq() call

[Tang, Changqing]

Hi,
        We are debuging our dynamic process code, when we call

ret = ibv_poll_cq(cq_hndl, 1, &compl);

The peer process may have destroyed the QP.

However, ibv_poll_cq() return -2 in 'ret', 'errno' is still 0

What could be the reason for this error ?

There is a posted send pending for completion, so error should be
reported via the completion status, not the polling function
itself.

Thanks for any help. This is OFED 1.3
