Hi David,

That's right. The hard Temac is a built-in hard core in virtex 4 FPGA.

I am working on that. But I am not so experienced and still working. :)

I don't think so. I think the hard and soft cores are similar. I have 
included the enet drive in Linux 2.4 and it works well. Now I am including 
the Temac in 2.6 and have not see the result.

I am doing that. So we can share our experience.
