QueueMax
(7:0)
This 8-bit value determines the maximum queue length with a
granularity of 64 cells.
The CPU programs the maximum queue length with a granularity of
64 cells by right shifting the value by 6:
QueueMax(7:0):= queuelength >> 6
The maximum length of any queue is limited to (255*64) = 16320
cells.
