What it means is that the IPFW code didn't see a long enough packet to
contain enough data to be logged usefully. That could be a sign of
hardware problems like a flaky cable or a NIC that is going wonky: if
you can check "netstat -i" and look for excessive input errors or
collisions.
If the machine is connected to a managed switch, look for "runt
packets", smaller than 54 bytes (56?, whatever the minimum valid size
is)....
