Cool. Linux 8.0. Where can I download it? I thought they are working on
getting 2.5.x stable and now they already is 8.0 :)

Why rate = 158 Kbit ??

Solution is easy. Make sure sum of child rates = parent rates.
So if you have 45 classes (from 1:5 to 1:50) and a total rate of 256kbit, then
use rate = 256kbit/45.
