Thanks for the info.
I cross compiled tc targeted to XSCALE platform. When i was trying to execute the tc commands that's when I encountered this invalid argument problem.
So now I understand, CBQ, HTB are kernel modules that needs to be loaded as well to use tc.
I have a few question:
1. Is there any packages for CBQ or HTB that I can just compiled for ARM again.
I dont want to compile the kernel again, so if I could get the CBQ & HTB packages, it'll make my life easier.
2. Aside from having these modules, what else should i add? (e.g.: config files, init scripts.. etc)
3. If at any case I uses both HTB & CBQ would it be okay if both of these modules are loaded?
Thanks for the time.

I don't know what "arm" is.
Are you certain that the CBQ module loaded? Yes, it should be a module,
not built into the kernel.
First make sure that there is only one TC executable on your system.
Then try a few different TC commands:
tc -s qdisc ls dev eth0
tc -s class ls dev eth0
tc qdisc add dev eth0 root handle 1: htb default 30
If the htb works then the problem is, of course, cbq. If both cbq and
htb fail but the "show" commands above work, then I can't help. But if
all fail, your cross compile was bad.
Also try
modprobe sch_cbq
modprobe -r sch_cbq
modprobe sch_htb
modprobe -r sch_htb
and watch your logs.
