As far as I know there&#39;s no Nios II implementation of the CS8900 driver. To make it work you would:

1) Copy the LAN91C111 component folder and rename as necessary to make the SOPC builder see it as a new CS8900 component.

2) Modify the LAN91C111 driver to work with the CS8900.

3) Figure out which lines from your new CS8900 component go to which pins on the daughtercard.

Not a simple task...
