Thanks, Thomas for forwarding this to the group.
I have one more question. Does DPDK QOS  uses any internal threads/timers
for the token bucket implementation?. The token
 buckets can be implemented in different ways.  When are the tokens are
filled, I see there is tb_period?
It looks like the tokens are filled when the HQOS thread is trying to find
the next active pipe?

Regards,
Satish Amara
