to the Switch Engine. Non-pause control frames are optionally filtered or forwarded.
When the receive FIFO is full and additional data continues to be received, an overrun condition occurs
and the frame is discarded (FIFO space recovered) or marked as a bad frame.
The receive MAC can be disabled from receiving all frames by clearing the
x MAC Receive Configuration Register
The size of the RX FIFO is 256 bytes. If a bad packet with less than 64 bytes is received, it will be
flushed from the FIFO automatically and the FIFO space recovered. Packets equal to or larger than
64 bytes with an error will be marked and reported to the Switch Engine. The Switch Engine will
subsequently drop the packet.
Receive Counters
The receive MAC gathers statistics on each packet and increments the related counter registers. The
following receive counters are supported for each Switch Fabric port. Refer to
Accessible Switch Control and Status Registers,” on page 212
Section 13.4.2.22
Total undersized packets
Total packets 64 bytes in size
Total packets 65 through 127 bytes in size
