We use the Temac driver from Grant's tree.
Nevertheless we changed the auto-negotiation code, as we had problem with
the default code when using the same code in U-Boot.
I have attached our auto-negotiation patch (nevertheless the old
auto-negotiation worked fine with the linux kernel, the main reason we
patched that is to hold the code base to maintain minimal).
