Revision 1.2
The priority of packets enqueued by the CPU are set by the CPU.
6.10.2 Priority Throttling
The Global Control register contains a “Priority Weight” field that controls the priority of the high priority queue ver-
sus the low priority queue. Options range from fair round robin (i.e. no difference in priority) to high priority (high
priority packets are always forwarded first). There are six priority weights between the highest and lowest
extremes as shown in Table 9.
