One thing to be careful about with MCI's:  in normal operation and
MCI will report more errors than older interfaces.  Collisions cause
fragments.  I have a feeling that the MCI sees these as individual
packets with errors, and older cards don't see them at all.  At any
rate, on busy networks, our MCI's show .1 to 1% input errors.
However tests with ping show pretty clearly that there are no actual
errors occuring.  We've tended to ignore input errors unless it gets
over 1% or there are other symptoms of problems.  This doesn't mean
that you have nothing to worry about.  I don't know your situation,
so I can't tell.  But simply the fact that you have higher rates
reported by the MCI than by older interfaces does not automatically
mean there are problems with the MCI's.
