under 9 bytes are not padded and are automatically dropped.
Automatic CRC Generation
The Automatic CRC Generation is used in conjunction with the padding feature to generate and
append a correct CRC to any incoming frame from the SPI4-2 interface. This feature is enabled by

Filtering of Receive Packets
This feature allows the MAC to filter receive packets under various conditions and drop the

5.1.2.3.1 Filter on Unicast Packet Match
This feature is enabled when bit 0 of the RX Packet Filter Control Register = 1. Any frame
received in this mode containing a Unicast Destination Address that does not match the Station
Address is marked by the MAC to be dropped. The frame is dropped if the appropriate bit in the

5.1.2.3.2 Filter on Multicast Packet Match
This feature is enabled when bit 1 of the RX Packet Filter Control Register = 1. Any frame
received in this mode containing a Multicast Destination Address which does not match the Port
Multicast Address is marked by the MAC to be dropped. The frame is dropped if the appropriate
bit in the RX FIFO Errored Frame Drop Enable register = 1. Otherwise, all multicast frames are
sent to the SPI4-2 interface, but with an EOP Abort code to the switch or Network Processor.
