QOSC00 through QOSC02 represents one set of values A-C for a 10/100 port when using the Weighted Random
Early Drop (WRED) Scheme described in Chapter 7.7. There are four such sets of values A-C specified in Classes
Byte Limit Set 0, 1, 2 and 3.
Each 10/ 100 port can choose one of the four Byte Limit Sets as specified by the QoS Select field located in bits 5
to 4 of the ECR2n register. The values A-C are per-queue byte thresholds for random early drop. QOSC02
represents A, and QOSC00 represents C.
Granularity when Delay bound is used: QOSC02: 128 bytes, QOSC01: 256 bytes. QOSC00: 512 bytes. Granularity
when WFQ is used: QOSC02: 512 bytes, QOSC01: 512 bytes, QOSC00: 512 bytes.
