Integrating WIZnet 6100 and the Nanostack Border Router

I’m in the process of intergrating the ARM nanostack border router and the external Ethernet chipset WIZnet 6100 to create my border router.

I’m having a few problems working out what is the best way to to implement the port by using either the ETH or the SLIP options as a template.

Any advise on which one I should be using or links to other documentation would be helpful.
