It detects the cable being removed and reinserted OK.

I can set the link speed and duplex fine using the "media=..." parameter 
on insmod.

My ADSL router doesn't have an interface (GUI or CLI) for setting the 
port speed and duplex. A Linksys WRT54GS wireless router is turning up 
tomorrow, so I may be able to set the port speed & duplex with that. But 
for now I can't test autodetection when the switch offers less than 
100Mbps full-duplex. I also have no GigE equipment to test with.

If I try setting the speed & duplex using something like this:

   ethtool -s eth0 speed 10 duplex half

it fails. I get no errors, but the "ethtool eth0" shows the link speed & 
duplex to be 100Mbps full-duplex. I think I managed to get it into 
100Mbps half-duplex once

When I try to "ethtool -s eth0 speed 10", the link lights on my ADSL 
router change to orange, which indicates 10Mbps. Then the light goes out 
and comes back green, which indicates 100Mbps.

So maybe the driver isn't waiting long enough for something.

Thanks, will do.
