Hi
Does it not make sense to print the mac address of the offending
oversize frame generator, so at least the host generating these
frames can be investigated?
FWIW, the arrival of these frames seem to lock-up the rl0 (on
5.2-CURRENT #25: Tue Mar 30) until a keypress on the console.
Is it safe to call ether_ntoa() at this point?
Ian
