You can also use the Avalon OpenCores 10/100 ethernet MAC. There is a full driver written for the InterNiche Stack that supports uCOSII and superloop modes of the stack.

The Avalon OpenCores MAC uses less resources than the Altera TSE MAC and there are no hard-coded device names in the driver that you need to worry about. There is a pretty good document explaining how to instantiate the MAC and get it up and running.

You can obtain the MAC and the driver from the NIOS forum:

The driver should work equally well for the regular OpenCores MAC should you decide to use it.

I have not used the 3C120 board but I have gotten both the OpenCores and TSE MAC running on the NEEK.
