The KSZ8893MQL/MBL will not forward the following packets:
1. Error packets
2. IEEE802.3x PAUSE frames
3. "Local" packets
December 2007
These include framing errors, Frame Check Sequence (FCS) errors, alignment errors, and illegal size
packet errors.
KSZ8893MQL/MBL intercepts these packets and performs full duplex flow control accordingly.
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."
