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)....
