I'll look into that, do you have any suggestions?

There are known problems with that configuration, that's why the newer drivers disable TSO for 10/100 speeds.
do you really think that you can see the performance gain fro musing TSO at those speeds anyway? we don't ;). In any case you should keep TSO off for 10/100 speeds.

we (the e1000 team) don't write drivers for the motherboard, but only for the NIC component, so I hope that answers your question.

I hit "reply-all" and I have no control over which field thunderbird removes or adds. I have to manually add your e-mail address too? Maybe your mail client is broken instead? Don't you want to receive replies?
