I'm unsure whether v7.2.x already automatically disables TSO for 100mbit speed link,
probably not. It should.
Please try our updated driver from http://e1000.sf.net/ (7.3.20) against the same
kernel. There are some changes with regard to the ich8/TSO driver that might affect
this, so re-testing is worth it for us.
also, please always include the full dmesg output. Feel free to CC
[email protected] on this.

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?

It disabled it but I enabled it just for fun.

I now run 7.3.20-NAPI.
BTW. the Makefile is buggy: it does not get CC from kernel's Makefile.
Using wrong compiler can cause for example a reboot when loading the module.
(At least that's what happened with gcc-2.95.3 vs 3.x.x some years ago...)

I enabled TSO again. I write again if TSO causes problems.
Why shouldn't it work with 100 Mbps? Not that it would help a lot,
but I ask this on principle.
/* disable TSO for pcie and 10/100 speeds, to avoid

Issues on the motherboard or the NIC?

loop-AES has some hacks which figure out the correct CC

No.
I was thinking that if TSO does not work at 100, why 1000 would be
any better. But I can't test at 1000 speeds right now.
But if you say driver is supposed to hang at 100 speed,
I believe you.
Ohh... that was fast.

I am subscribed to the mailing list.
That's why my email was not in Mail-Followup-To.
But if your thunderbird does not support Mail-Followup-To,
just ignore it. I can add the header field manually.
