Alexey, when you had checksum problems, did you see invalid checksums in
tcpdump?

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. :-)

Does anyone else have an idea or suggestion I can try?

Well, let's look what exactly checksum routines calculate on the steps.
Maybe, this will give a clue.

Just tell me what you want me to dig out from the checksumming stuff.

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. :-)

hehe, this isn't a clone, it's a quad with "Digital DS21143 Tulip rev
65" chips (from tulip driver) behind a "PCI bridge: Digital Equipment
Corporation DECchip 21152" (from lspci)

Never argue with an idiot. They drag you down to their level, then beat
you with experience.
