[wplug] Determine network link speed

[Jason Dunn]

I'm trying to find a way to tell what the link speed is on a machine
running RH8. I know with ifconfig, you can tell it what media type to
use, but I want to view the speed an auto selecting card is selecting. 
The switch that the machine is connected to is in a cabinet and is
unreachable.  Is there any way to tell whether it's running at 10BaseT
or 100BaseT?

Thanks,
Jason
