Broadcast storm protection
A port of IP178C begins to drops broadcast packets if the received broadcast packets are more than the
threshold defined in MII register 31.9[15:14]
or EEPROM register
83[7:6]
bq_stm_thr_sel [1:0] in 10ms
(100Mbps) or 100ms (10Mbps)
The function can be enabled by pulling high pin 91 BF_STM_EN or programming MII register 30.1.[6].
IP178C handles multicast frame as a broadcast frame in broadcast storm protection function if pin 77
BCSTF is pulled low.
