I have a 3c509B card in a co-located machine. Since we moved
from a location with a 10Mbps switch/hub to a 100Mbps switch,
the computer falls off the network every few days. Also, the
link light on the back of the card does not light up, and
the switch only sees it as 10Mbps.

Currently, the switch is forced to 10Mbps half-duplex, and
that gave me a week rather than two days of uptime... It has
been fixed by downing and upping the port on the switch, but
it's starting to get annoying. :-) Before I try the 3com
GPL'd driver (which means kernel rebuilding and whatnot) I
thought I'd ask if this was a known or obvious problem.

I got the latest mii-diag and vortex-diag programs from the
scyld site as suggested elsewhere in the list archives, and
here's what they gave me:

These were done over the ssh link so I _know_ I have link...
(BTW, should these be done with the link down? It'll be a
hassle to get to the box and do them locally, but if I have
to I have to)
