The intent is right, but the result here is wrong.  Unfortunately, 1500
byte packets are rare.  About 6.9% of the traffic (by packet).  Yes, it
would triple that fragment of the traffic.  However, that would not affect
the other (much more common) packet sizes in the distribution.

If you wanna worry about the number of packets in the net, worry about the
40 byte packets.  Dem's da killas.  ;-)
