Pri_2Q[1:0]
(Note that program
Prio_2Q[1:0] = 01 is not
supported and should be
avoided)
When the 2 Queues configuration is selected, these
Pri_2Q[1:0] bits are used to map the 2-bit result of
IEEE 802.1p from register 128/129 or TOS/DiffServ
from register 144- 159 mapping (for 4 Queues) into
two queues low/high priorities.
2-bit result of IEEE 802.1p or TOS/DiffServ
00 (0) = map to Low priority queue
01 (1) = Prio_2Q[0] map to Low/High priority queue
10 (2) = Prio_2Q[1] map to Low/High priority queue
11 (3) = map to High priority queue
Pri_2Q[1:0] =
00: Result 0,1,2 are low priority. 3 is high priority.
10: Result 0,1 are low priority. 2,3 are high priority
(default).
11: Result 0 is low priority. 1,2,3 are high priority.
