Hi,

Our NIC hardware provides a QoS tree for each link with strict
priority and DRR scheduling & traffic shaping at each level. I'm
curious what the closest qdisc that has the aforementioned
functionalities for offloading to hardware. I looked into htb/drr/prio
qdiscs, but each qdisc supports a subset of the functionality enabled
by our hardware.

Is the ETS - Enhanced Transmission Selection scheduler a better fit if
we simply need to offload scheduling with strict priority and DRR?

Thanks,
Naveen
