Yes, we did realize that rte_sched is not suitable for AQM algorithms.
We have implemented a bare-bones AQM mechanism that is independent of rte_sched.
Using this implementation we have successfully added and tested PIE and CoDel.

CAKE can be added using what we have built, but before we do that we wanted
to know if such a feature would be welcomed by the community. Subsequently,
we will submit an RFC patch series to the dev mailing list.

Thanks,
Archit Pandey.
