I would like to make another point about why I am making this change
in case it is not clear. The queue full events are form
TRANS_TX_CREDIT_TIMEOUT_ERR and TRANS_TX_CLOSE_NORMAL_ERR errors in
the slot: I want the slot retried when this occurs, so I set status
as SAS_QUEUE_FULL just so we will r

In high-datarate aging tests, it is found that
the SCSI framework can periodically
issue lu resets to the device. This is because scsi
commands begin to timeout. It is found that TASK SET
FULL may be returned many times for the same command,
causing the timeouts.
