Maybe your question should have been more specific :-) - I did also
misunderstand your e-mail as "can it do full-duplex".

As for the errors:

"runts" are "too short packets" - those can be a sign of bad cabling, bad
ethernet hardware, or "noise".  Possibly they could be reminders of 
packets after collisions/late collisions.

If the interface "pings" fine, I wouldn't worry about it - if it has
packet drops on an extended ping, try changing the cables.
