Thanks Stephen.

             While browsing the DPDK qos code, i figured out that existing PIPE-PROFILE cannot be updated or deleted at run time. 
Was there any reason why this limitation ?

Thanks

No. Current qos sched code has hard coded assumptions on number of pipes etc.
I think it is modeled after some carrier standard and is not generally
that useful.
