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 setting bit 6 of the
When padding of undersized frames on transmit is enabled, the automatic CRC generation
must be enabled for proper operation of the IXF1110 MAC.
Filtering of Receive Packets
This feature allows the MAC to filter receive packets under various conditions and drop the
packets via an interaction with the Receive FIFO control.
Jumbo frames (1519 - 9600 bytes) matching the filter conditions, which would cause the
frame to be dropped by the RX FIFO, are not dropped. Instead, jumbo frames that are
expected to be dropped by the RX FIFO, based on the filter settings in the
Control ($ Port_Index + 0x19), on page
EOP abort frame. Jumbo frames matching the filter conditions are not counted in the RX
FIFO Number of Frames Removed Register because they are not removed by the RX
FIFO. Only standard packet sizes (64 - 1518 bytes) meeting the filter conditions set in the
RX Packet Filter Control ($ Port_Index + 0x19), on page 131
RX FIFO and counted in the RX FIFO Number of Frames Removed.
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 RX FIFO Errored Frame Drop Enable Register = 1. Otherwise, all
unicast frames are sent to the SPI4-2 interface, but with an EOP Abort code to the switch or
Network Processor.
The VLAN filter overrides the unicast filter. Thus, a VLAN frame cannot be filtered based on
the unicast address.
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.
Filter Broadcast Packets
This feature is enabled when bit 2 of the
Any broadcast frame received in this mode 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 broadcast frames are sent to the SPI4-2 interface, but with an EOP Abort
code to the switch or Network Processor.
