Talking to another rc3 kernel with tg3 tso on is as fast as tso off now. Unfortunately the ACKs still look funny.
Can you help us debug this instead of just running tests over and over Andi? It's frustrating because I cannot reproduce the problem here, else I would be adding checks to the receiver on my systems here. :-/ Please put some checks into the ACK tests on your 2.6.5 receiver to determine why it does not want to ACK every other frame like it is supposed to. We need to figure out where the stretch ACKs are coming from. Thanks.
