The KSZ8895MQ/RQ/FMQ will not forward the following packets:
1. Error packets
These include framing errors, Frame Check Sequence (FCS) errors, alignment errors, and illegal size packet errors.
2. IEEE802.3x PAUSE frames
KSZ8895MQ/RQ/FMQ intercepts these packets and performs full duplex flow control accordingly.
3. "Local" packets
Based on destination address (DA) lookup, if the destination port from the lookup table matches the port from which
the packet originated, the packet is defined as "local."
