Hi,
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.

Grace
