diffserv EF PHB can be realized by any queueing discipline able to
guarantee the assigned rate.  In ALTQ, PRIQ, H-FSC and CBQ can be
used.

diffserv AF PHB can be realzied by combining a marker (trTCM or tswTCM
in ALTQ) and a buffer management mechanism (RIO in ALTQ).
RIO can be used with PRIQ, H-FSC and CBQ.
