   It seems intuitively more efficient for a flow classifier
   to use a single host-defined flow identifier than having
   to walk a potentially long list of extension headers. 
   Another advantage is that, sort of like diffserv, the
   host itself can decide what is to be grouped in a particular
   flow instead of requiring that it match the normal 5-tuple.
