BQ_HWM_0_SEL
,
Broadcast Queue high water mark threshold selection. IP175 will
drop the incoming broadcast packet if the broadcast packet
count exceeds the threshold.
If (register 02H[2]: bf_stm_en==1), its corresponding threshold is
00:1024, 01:256, 10:128, 11:48,
If (register 02H[2]: bf_stm_en==0), the function is disabled.
Reserved
OQ_THR, Output Queue threshold
An incoming packet will be dropped if the number of packet
queued in destination port is over the output queue threshold.
IP175 enables this function automatically only if there is no flow
control.
