QOSC03 through QOSC05 represents one set of values A-C for a 10/100 port when using the Weighted Random
Early Drop (WRED) scheme.
Granularity when Delay bound is used: QOSC05: 128 bytes, QOSC04: 256 bytes, QOSC03: 512 bytes. Granularity
when WFQ is used: QOSC05: 512 bytes, QOSC04: 512 bytes, QOSC03: 512 bytes.
