make pf use one mbuf tag instead of 6 distinct ones. use a little struct
in the data part for the data from the previously distinct tags.
look up the tag early and carry a pointer to it around.
makes the code easier and saves some tag lookups and thus helps performance,
as proven by tests run by Schberle Dniel <Schoeberle.Daniel@aamtech.hu>
Initially hacked up somewhere over the atlantic ocean in an A330
early testing reyk and moritz, "put it in" theo
