The 2.5 Gbps Ethernet FIFO is available for MAC data rates of 2.5 Gbps only. It is described in the following files:
<component_name>_two_g5_eth_fifo.v[hd]
<component_name>_tx_client_fifo_2g5.v[hd]
<component_name>_rx_client_fifo_2g5.v[hd]The 2.5 Gbps Ethernet FIFO contains an instance of
tx_client_fifo_2g5 to connect to the MAC TX AXI4-Stream interface, and an instance of the rx_client_fifo_2g5 to connect to
the MAC RX AXI4-Stream interface. Both transmit and receive FIFO
components implement an AXI4-Stream user interface, through which the
frame data can be read/written. The AXI4-Stream user interface is 32 bits
wide and the MAC TX/RX AXI4-Stream interfaces are eight bits wide.
