[LARTC] cbq parameters

[LARTC] cbq parameters

[Leandro Stasi]

If I create a cbq qdisc as a leaf of a cbq class, the bandwith rate is 
the same of the root cbq qdisc or the rate of the cbq class?

Does exist the parameter rate on the "tc qdisc add" for cbq command?

tc qdisc add dev eth0  root handle 1:0 cbq bandwidth 10mbit avpkt 1000 
cell 8

tc class  add dev eth0  parent 1:0 classid 1:3 cbq bandwidth 10mbit rate 
50kbit allot 1514 cell 8 maxburst 20 avpkt 1000 isolated bounded

tc qdisc add dev eth0  parent 1:3 handle 3:0 cbq bandwidth 10mbit  rate 
50kbit avpkt 1000 cell 8

It's not recommended to add a cbq qdisc on a cbq class.  It's better to bound 
the first class and add the class to the bounded class in stead of adding a 
second qdisc.  Cbq (and htb) are not made (designed) to be attached on a leaf 
class.

only note, as of HTB 3.6 it detects non-work conserving discipline
as leaf and should work ok (only will eat more cpu).

I love htb :)
