Queue Algorithm
Modifier
The queue algorithm modifier field specifies restrictions
on the algorithm used for reordering commands that are
tagged with the Simple Queue Tag message.
DQue
A Disabled Queuing bit of 1 indicates that command
queuing is disabled.
A Disabled Queuing bit of 0 indicates command queuing
is enabled.
A value of zero (0) in this field specifies that the target will order the
actual execution sequence of the commands with a SIMPLE QUEUE
TAG such that data integrity is maintained for that initiator.
A value of one (1) in this field specifies that the target may reorder the
actual execution of the commands with a SIMPLE QUEUE TAG in any
manner.
