slow receive with 3cSOHO100-TX card / 3c59x drivers

Hi.  I'm having trouble with my network card drivers.  I seem to be
able to send a 50MiB file in about 5-7 seconds, but it takes 18-20
seconds to receive it.  I've isolated it down to this computer, and
the 3c59x drivers.

I'm using a recent MEPIS linux, which is based off of debian.  With
kernel 2.6.7 and 2.6.10, I get the above-described behavior.  With
kernel 2.4.26, it seems to work alright!

I did a bunch of searching, but couldn't find an answer.  I did see
something about 'mii-diag' or 'mii-tool', though, so I tried that. 
That seems to give some hint.

Could anyone comment on this?


Thanks a bunch!
Mike
