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."
