Can anyone with more experience in traffic shaping on Linux help me? I
have a few problems with tc-htb and I can't solve them and the docs
are really sparse (the lartc-howto doesn't help much :( )

If I have this simple example like this:

tc qdisc add dev eth0 parent root handle 1: htb
tc class add dev eth0 parent 1: classid 1:100 htb rate 192kbit
tc qdisc add dev eth0 parent 1:100 handle 100: htb default 1
tc class add dev eth0 parent 100: classid 100:1 htb rate 64kbit
tc class add dev eth0 parent 100: classid 100:2 htb rate 128kbit

Does the 100: qdisc inherit the 192kbit rate limit of 1:100?`

Then, if I try to add a filter like this:

tc filter add dev eth0 protocol ip parent 1:100 u32 \ 
	match ip src 1.2.3.4 flowid 100:1

Nothing happens. Why? If I attach it to root (or 1:0, or 1:) it shows,
but I want to attach it to 1:100. How can I do that?

Last, if I add this (again, just an example):

tc qdisc add dev eth0 parent 100:2 handle 200: prio bands 3

Why does 'tc class ls dev eth0' list the three bands like this:

class prio 200:1 parent 200: [UNKNOWN]
class prio 200:2 parent 200: [UNKNOWN]
class prio 200:3 parent 200: [UNKNOWN]

If I add a qdisc to a band, for example like this:

tc qdisc add dev eth0 parent 200:1 handle 300: sfq perturb 10

It shows like this:

class prio 200:1 parent 200: leaf 300: [UNKNOWN]

What does the [UNKNOWN] relate to?

I'd appreciate any help anyone could offer. This thing is starting to
get at me.
