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
