I believe thomas would like to see more use of flow label, like
for every TCP sessions. though there's no guarantee that flow label
will identify each of TCP sessions (intermediate routes cannot trust
the behavior of TCP endpoints), flow label should give thomas
a good indication for doing layer 4 classification.
