IXF1110 10-Port 1000 Mbps Ethernet Media Access Controller
Note:
5.1.2.3.3
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.
5.1.2.3.4
This feature is enabled when bit 3 of the
VLAN frames received in this mode are 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
VLAN frames are sent to the SPI4-2 interface, but with an EOP Abort code to the switch or
Network Processor.
5.1.2.3.5
This feature is enabled when bit 4 of the
PAUSE frames received in this mode are marked by the MAC to be dropped. The frame is dropped
if the appropriate bit in the
PAUSE frames are sent to the SPI4-2 interface.
5.1.2.3.6
This feature is enabled when bit 5 of the
Frames received with an errored CRC are marked as bad frames and may optionally be dropped in
the RX FIFO. Otherwise, the frames are sent to the SPI4-2 interface and may be dropped by the
switch or system controller (see

When the CRC Error Pass Filter bit = 0
takes precedence over the other filter bits. Any packet (Pause, Unicast, Multicast or Broadcast
packet) with a CRC error will be marked as a bad frame when the CRC Error Pass Filter bit = 0.

Table 14, “CRC Errored Packets Drop Enable Behavior” on
Packets are passed to the SPI4-2 interface. They are not marked
as bad and are sent to the switch or Network Processor.
Packets are marked as bad but not dropped in the RX FIFO. These
packets are sent to the SPI4-2 interface, but with an EOP Abort
code to the switch or Network Processor.
Packets are not marked as bad and sent to the switch or Network
Processor, regardless of the Frame Drop En setting.
PAUSE Packets are marked as bad, are dropped in the RX FIFO,
and never appear at the SPI4-2 interface.
