Nullified UTRD, Host controller skips this transfer request, reply Completion Queue entry to Host SW with OCS=ABORTED 2. SQ cleanup, The host controller will post to the Completion Queue to update the OCS field with ABORTED. For these two cases, set a flag to notify SCSI to requeue the command after receiving OCS_ABORTED.
