QOSC35 through QOSC32 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. QOSC35 corresponds to W3 and QOSC32
corresponds to W0.
QOSC32[7:6]: Priority service type for the ports select this parameter set. Option 1 to option 4.
QOSC33[7]: Priority service allow flow control for the ports select this parameter set.
QOSC33[6]: Flow control pause for best effort traffic only

QOSC40 through QOSC47 represents the set of WFQ parameters for Gigabit port 24. The granularity of the
numbers is 1 and their sum must be 64. QOSC47 corresponds to W7 and QOSC40 corresponds to W0. In the 2G
trunk configuration, the sum of all values QOSC40 through QOSC47 must be equal to 128.
