Mike Marciniszyn c0af2c057d IB/qib: Prevent double completions after a timeout or RNR error ... There is a double completion associated with error handling for RC QPs. The sequence is: - The do_rc_ack() routine fields an RNR nack and there are 0 rnr_retries configured on the QP. - qib_error_qp() stops the pending timer - qib_rc_send_complete() is called from sdma_complete() - qib_rc_send_complete() starts the timer because the msb of the psn just completed says an ack is needed. - a bunch of flushes occur as ipoib posts WQEs to an error'ed QP - rc_timeout() calls qib_restart_rc() - qib_restart_rc() calls qib_send_complete() with a IB_WC_RETRY_EXC_ERR on a wqe that has already been completed in the past The fix avoids starting the timer since another packet will never arrive.
