This patch follows the logic from ib_core but considers the internal device state upon executing the involved commands. Specifically, Upon internal error state modify QP to an error state can be assumed to be success as each in-progress WR going to be flushed in error in any case as expected by that modify command. In addition, As the drain should never fail the driver makes sure that post_send/recv will succeed even if the device is already in an internal error state. As such once the driver will supply the simulated/SW CQEs the CQE for the drain WR will be handled as well. In case of an internal error state the CQE for the drain WR may be completed as part of the main task that handled the error state or by the task that issued the drain WR. As the above depends on scheduling the code takes the relevant locks and actions to make sure that the completion handler for that WR will always be called after that the post_send/recv were issued but not in parallel to the other task that handles the error flow.
