Gigabit or not? SiS 190 integrated ethernet.

[Neil Woolford]

I have an AMD Athlon based motherboard, with a built-in pci ethernet adaptor
that reports itself as a SIS 190 Gigabit ethernet adaptor.

However, when I connect it to a gigabit switch, it is reported (by the status
led) as a 10/100 device, which is indeed the speed it is clearly running at.

The computer is running an Ubuntu Gutsy system, updated to current.

Is there any kind of specialised driver or non-default configuration needed to
get Gigabit speeds out of this adaptor, or is it just misnamed?
