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.
12.7.28 Classes WFQ Credit Set 1
Accessed by serial interface (R/W)
W0 - QOSC28[5:0] – CREDIT_C10 (CPU Address 533)
W1 - QOSC29[5:0] – CREDIT_C11 (CPU Address 534)
W2 - QOSC30[5:0] – CREDIT_C12 (CPU Address 535)
W3 - QOSC31[5:0] – CREDIT_C13 (CPU Address 536)
QOSC28 through QOSC31 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. QOSC31 corresponds to W3 and QOSC28
corresponds to W0.
QOSC28[7:6]: Priority service type for the ports select this parameter set. Option 1 to 4.
QOSC29[7]: Priority service allow flow control for the ports select this parameter set.
QOSC29[6]: Flow control pause best effort traffic only
12.7.29 Classes WFQ Credit Set 2
Accessed by serial interface (R/W)
W0 - QOSC32[5:0] – CREDIT_C20 (CPU Address 537)
W1 - QOSC33[5:0] – CREDIT_C21 (CPU Address 538)
W2 - QOSC34[5:0] – CREDIT_C22 (CPU Address 539)
W3 - QOSC35[5:0] – CREDIT_C23 (CPU Address 53a)
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.
