Now that we have a means to perform a UDP socket lookup without taking
a reference, it is feasible to have flow dissector crack open UDP
encapsulated packets. Generally, we would expect that the UDP source
port or the flow label in IPv6 would contain enough entropy about
the encapsulated flow. Howe
