Usage Information
You can configure all the data queues. You can configure queues 0-7.
The following table describes the mapping between the threshold weight of the shared buffer on the queue. It
also shows the percentage of the available shared buffer used by the queues for each of the corresponding
threshold weights of the shared buffer:
