Just to annoy you a little more, I have lots and lots of Linux boxes
with 3C905B (3c59x driver) and 3c905C (3C90X driver from 3COM), some
EEPro 100 and some tulip boxes behind Cisco 2924XL switches and none
of them show these symptoms from 2.0.35-2.0.39 and 2.2.1 to 2.2.16pre2.

The Ciscos do need some tweaking, though, on some of the boxes I had
to disable auto-negoiation.
