QOSC12 through QOSC17 represent the values A-F for Gigabit port 2. They are per-queue byte thresholds for
random early drop. QOSC17 represents A, and QOSC12 represents F.

QOSC24 through QOSC27 represents one set of WFQ parameters for a 10/100 port. There are four such sets of
values. The granularity of the numbers is 1, and their sum must be 64. QOSC27 corresponds to W3 and QOSC24
corresponds to W0.
QOSC24[7:6]: Priority service type for the ports select this parameter set. Option 1 to option 4.
QOSC25[7]: Priority service allow flow control for the ports select this parameter set.
QOSC25[6]: Flow control pause best effort traffic only
Both flow control allow and flow control best effort only can take effect only the priority type is WFQ.
