Missing items in board_spec.xml for Cyclone V SoC Dev Board

I have a Cyclone V SoC dev board and am trying to work out how to 'connect' the two Ethernet ports in my kernel.

The AOCL programming guide indicates that the board_spec.xml file should contain lines such as the following:

<channels>

<interface name="udp_0" port="udp0_out" type="streamsource" width="256" chan_id="eth0_in" />

</channels>

However my board_spec.xml dos not have any such interfaces.

Do I have an incorrect board_spec.xml file? Is there any way to update it?

Thanks in advance
