[TriLUG] Ethernet Question

[Steve Kuekes]

No collisions or errors on the TX or RX and this machine has been up 
 >100 days.  The adapter that is giving the slowdown is a 1000/100/10 
speed adapter as well.  Its running the sk98lin driver.  Maybe I need a 
different driver for the adapter (Its on the motherboard).

I tried running the mii-tool package and I get an error on the eth0 adapter

SIOCGMIIPHY on 'eth0' failed: Bad address

It works fine on the eth1 in the same machine.
