QOS mode selection
(Default 00)
Determines which of the 4 sets of QoS settings is used for 10/100 ports.
Note that there are 4 sets of per-queue byte thresholds, and 4 sets of WFQ
ratios programmed. These bits select among the 4 choices for each 10/100
port. Refer to QOS Application Note.
00: select class byte limit set 0 and classes WFQ credit set 0
01: select class byte limit set 1 and classes WFQ credit set 1
10: select class byte limit set 2 and classes WFQ credit set 2
11: select class byte limit set 3 and classes WFQ credit set 3
