Hello!

No. It is dubiously similar to your case. It is the sibj
"Linux TCP problem while talking to hostme.bkbits.net" in linux-kernel.
It is mistique not less than your case. :-)

Well, let's look what exactly checksum routines calculate on the steps.
Maybe, this will give a clue.
Actually, tulip is really different of another cards, this creature
generates badly aligned packets. F.e. it is possible a checksumming routine
folds some bytes beyond end of frame. :-) I have lots of verious tulips here,
but have never seen such a shit. :-)
