[9fans] unrecognized ethernet card

[Bela Valek]

Hi Everybody,

I installed Plan 9 on a new computer (Erik's 9atoms.iso), it doesnt
recognize the ethernet device (there is no /net/ether0). I wonder if
something can be done. If changing configuration doesnt help, I hope
its similar enough to an already supported device, so a few changes
here and there can make it work.

By the way, I was also wondering, when will Erik's SATA support arrive
in the main distribution?

Anyway, here are the details of the unrecognized device, from Linux:

i'm sorry, there's no support for nvidia ethernet.
i don't know if docs are available, but the part
itself seems easy enough to program.  unfortunately,
the driver needs to do a lot of phy setup.
