Just out of curiosity: have you looked at the Linux `forcedeth'
driver? I haven't, but if it really works, and nVidia is sending the
developers diffs, then maybe the info there will enough to write a
full-source, BSD-licence *BSD driver?
Just a thought.

Have you tried pinging 188.8.131.52?

I skimmed this very quickly. a few quick comments:
I didn't understand the check for an `rl' parent device: If you're
using that phy with the nforce ethernet driver, does the nforce attach
as some kind of `rl'. or an `nv', or what? Am I missing something?
Also, if we did import this, we should rip out the corresponding code
from the 81x9 driver (we don't want to duplicate it).
Last: does the FreeBSD driver work with the gigabit Nvidia Ethernet?
Have you tried it? Will it need yet more PHY support?

Hence my (perhaps ignorant) question about the `forcedeth' driver....
writing a driver based on that would be one way around all the GPL issues.
