The KSZ8842M will not forward the following packets:
Micrel, Inc.
October 2007
1. Error packets.
2. 802.3x pause frames.
3. "Local" packets.
These include framing errors, Frame Check Sequence (FCS) errors, alignment errors, and illegal size packet
errors.
The KSZ8842M intercepts these packets and performs the flow control.
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."
