    If it were a problem there might be a solution, but collisions
    are not a problem, they're normal on an ethernet. When you
    read "collision" you think "error." You must retrain your mind,
    collisions are normal operating procedure on ethernet. Really.
    If the collisions were above 10%, it would be cause for concern;
    at 0.03% I can only conclude that you have a switched ethernet
    and have occasional broadcast traffic. 0.03% is way too low for
    any half-duplex (i.e. built with hubs) network.

    Repeat after me: "Collisions are normal on ethernet. 0.03% is
    nothing to be upset about."
