I'll take this into account too... BTW I tried to change the w98 window
size thru registry string, but it doesn't appear to work. w98 window
stays stubbornly at 8k.

More news of that:
a) I swapped the two AMD PC-net32 pci cards and changed the cable, soon
to find that I was getting the same asymmetric performance
(linux-->win98: 9-25 kb/s, win98--->linux: 500-600 kb/s).
moreover the same mysterious "cable errors" started happening again from
time to time.
I then remembered having read something about strange things happening
when two lone pc-net32 cards were facing each other... and amd posting
driver fixes for that
So I popped in an old dusty NE200 clone instead of the PC-net32 and set
the adequate module options to load it. No other config changes.
I ftp from the win98 machine
ftp get: linux--->w98 779.7 kb/s :-)
ftp put: w98--->linux 374.75 kb/s
that's better...
same performance improvement for samba excepted for smbclient puts (??)
that's somewhat better and nearer of what I expected.
I get some receive frame errors I'll have to investigate, and some
collisions, which is normal. No more carrier errors.
So my current assessment of the problem is:
There's something wrong with the amd pc-net32 card or its linux driver.
This hasn't apparently to do with any single netcard since I swapped the
cards and the same behaviour was observed in the same machine. If it was
a single netcard problem, it would have surfaced on the other side.
This error appears when two pc-net32 cards are talking to each other in
a single lan
Looking for someone with a similar config who can reproduce this
behaviour...
I'm off for one month but I'll continue to troubleshoot this after march
8.
Do answer to my personal address it'll be faster than to wad thru the
collected messages from the list.
thanks to all,
Max K.
