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.
