Traffic Control problems

[Ian Pushee <bright@giantsquid.net>]

I am trying to get traffic control (aka: bandwidth limiting) working on 
my server, so that downstream users can't monopolize the upload 
bandwidth and steal resourses from essential services like web and mail 
hosting. I am trying to make it work based on the HTB script in the 
"Linux Advanced Routing & Traffic Control HOWTO". Unfortunately I can't 
get past the first real step -- creating the qdisc root class:

> tc qdisc add dev eth2 root handle 1: htb default 26
RTNETLINK answers: Invalid argument

I have traced the problem to specificly trying to add an HTB qdisc, 
because I can add a CBQ just fine:

> tc qdisc add dev eth2 root handle 1: cbq avpkt 1000 bandwidth 10mbit

I running the testing branch 2.4.20 kernel, patched only with the patch 
for my achetecture (ppc). I've tried it using HTB both compiled directly 
into the kernel, and as a module (when used as a module, the sch_htb.o 
module loaded automaticly when I ran the above line, but was being used 
by 0 processes after the error).

Any help or suggestions would be greatly appreciated.

Thanks,
