Yep.  that's how "tc" works.  When you use mbit provide a speed, it's kilo 
bit/s.  When you use mbit to provide a packet size, it's kilo bit.

I suppose you mean chapter 9.6
1: = 1:0 = qdisc (second number is zero)

[LARTC] Remarks about the HOWTO

[Laurent Foucher]

Hello,

I have some remarks about the chapter 9 :

* At the beginning, the term "mbit" appears with two differents
definitions (kilo bits/s and kilo bit).

* In the chapter about pfifo_fast, the table that give the values of
TOS, the Linux priority and the band. I don't understand why the last
column (band) is different  of the default priomap given just after (on
the commandline).

* In the chapter, "How filters are used to classify traffic", the tree.
What's represent the numbers ? Are they the handles of the classes or
the handles of the qdisc ? It's not really clear for me.

* I haven't very well understood the chapter "How packets are dequeued
to the hardware". I don't understand if all the classes are quering or
not ? Well, i think that this chapter is not clear enough.

Hope that these remarks will improve the HOWTO,

Regards,

Laurent Foucher
