Looks like you have a duplex mismatch somewhere.  If your linux box is
attached to a hub, you should be running half-duplex.  If you're running
off a true switch, force both the switch port and the linux box to full
duplex.

On a clean 100mbit FD network you should see almost 0 errors and 0
collisions.

On a clean 100mbit HD network you should see almost 0 errors and <5%
collisions.
