The KS8993M will not forward the following packets:
1. Error packets. These include framing errors, FCS errors, alignment errors, and illegal size packet errors.
2. 802.3x pause frames. The KS8993M will intercept these packets and perform the appropriate actions.
3. "Local" packets. Based on destination address (DA) lookup. If the destination port from the lookup table
