Teredo bubbles are IPv6 packet with no next header, so 40 bytes.
Echo requests have no specified size; I believe Windows uses 4 bytes
of request payload, so 40+8+4 = 52 bytes, but... an other stack
uses a larger value.
In any cases, attempt to "mess" with these "signalling" packets
would likely wreak havoc to backward compatibility.
