Re: [LARTC] Problen in cbq , fw

Pawanji,

 Aapka yeh config tho thik hai. This config seems to be perfectly fine,
why don't you try htb + u32 and see the comparitive results you get.

 This isn't a solution to your problem though. Setting up the same is a
breeze and it does the job more than well.
