TCP/UDP Bad Checksum

Hi,

I've got a problem with my ethernet frames:

The ping and DHCP client work fine as same as the TCP handshake, so the
connexion is established fine. But when the frame (TCP or UDP) send by my
board need a checksum, this checksum failed and the server don't respond me.

I have adapted the ethernet drivers for 2.4 kernel to 2.6 so it might come
to it but my ethernet controller don't have checksum offload; and I use a
2.6.20 kernel.

I have no idea where search. So if you could give me some way where might be
the issue, I'll really appreciate...

Thanks,
Guillaume Berthelom
