tulip driver again

Jeff> Yes, please do.

Hi Jeff,
I have a Digital Tulip card that fails to work in recent kernels.
There seems to be a problem with normal-sized packets.

On 2.5.7, this is what I see:

ping -s 70 works;
ping -s 71 gives
`wrong data byte #70 should be 0x46 but was 0x0' ping -s 79 doesn't work.

ping -s 70 works
ping -s 71 does not work.

Here's the lspci -vvvn output

Here's the messages from the kernel:

Jeff> The more bug reports I can receive (in private or CC'd to lkml), Jeff> the better picture I get. If you have multiple tulips, feel Jeff> free to email reports on those too :)

Jeff> Best output is: lspci -vvvn dmesg, after updating Jeff> drivers/net/tulip/tulip.h TULIP_DEBUG to 5, and recompiling Jeff> tulip-diag -mmaavvveef
