Hi!

Does it make sense to create a prio qdisc and attach an
htb qdisc to it? I'm thinking of a configuration like:

                  root
                   |
	  +----- prio 1: -----+
          |        |          |
         1:1      1:2        1:3
          |        |          |
      sfq 11:   htb 12:   sfq 13:
                   |
       +-------- 12:1 ---------+
       |     /     |     \     |
      100:  101:  102:  103:  104:  all sfq qdiscs

Really high priority traffic (VoIP) should go to 11:,
normal traffic (and bandwidth limited) to 101:-104:,
low priority traffic (which may starve) to 13:.

Q1: Is this really neccessary or is HTB alone sufficient
    (i.e. attaching 12: to the root qdisc) by setting
    proper priorities to 100:-104: ?

Q2: Do I attach all filters to 1: or should I attach
    to 1: and 12: as required?

Q3: What about performance with an hierarchy like that?
    Will this be an issue?

Regards, Walter
