When TRANS_TX_ERR_FRAME_TXED error occurs in a slot, the command should be re-attempted. This error is equivalent to meaning that the queue is full in the sdev (and not the host). A superflous debug statement is also removed in the slot complete handler. Signed-off-by: John Garry <john.garry@huawei.com> Reviewed-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Martin K.
