	Field Pair	Register[Bits]	Field	Value	Description
	TX_Queue_Map0	TX_QUEUE_CNTL0[3–0]	Queue Pointer	0h to Fh	Pointer to a queue. This pointer can be
					programmed to point to any one of the 16
					TX buffer descriptor queues.
		TX_QUEUE_CNTL0[7–4]	Number of Msgs	0h to Fh	Number of contiguous messages
					(descriptors) to process before moving to
					TX_Queue_Map1.
	TX_Queue_Map1	TX_QUEUE_CNTL0[11–8]	Queue Pointer	0h to Fh	Pointer to a queue. This pointer can be
					programmed to point to any one of the 16
					TX buffer descriptor queues.
		TX_QUEUE_CNTL0[15–12]	Number of Msgs	0h to Fh	Number of contiguous messages
					(descriptors) to process before moving to
					TX_Queue_Map2.
