There are known auto-neg problems with Apple eth. chips. We should
provide a way to force the driver duplex and speed modes. I beleive an
ioctl along with a small command line tool would be cool, but maybe not
enough (a compile option or kernel command line args would help for
people netbooting).

I've not find "standard" ioctl I could implement for that, so I beleive
we just can invent a new one and add it to MACE, BMAC and GMAC drivers.
I'll look into this when I'm back along with some GMAC fixes.
