You forgot to check that pipe BE TC rate is not bigger than the pipe rate, which is a check that is enforced for the other higher priority traffic classes.

The TC_OV logic should be enabled for all the configuration/initialization code; the only place it should be conditionally enabled is the run-time code (e.g. grinder update/schedule), so no need for this #ifdef here. Same in many other places, should be easy to change for a consistent approach.

Ouch, this is a bug! The queue parameter of public function rte_sched_port_pkt_write() is not the "queue within the pipe" (0 .. 15), it is actually the "queue within the traffic class" (0 for high priority TCs, 0 .. 3 for BE TC), as explained in the API Doxygen description.
You removed the traffic class parameter in the above rte_sched_port_qindex, we should put it back and keep the initial meaning of the queue parameter for the _qindex function, which is internal function.
The way to quickly fix this is simply having a per-port pre-computed small table of 16 entries indexed by the traffic class ID and provides the ID of the first pipe queue of that traffic class; then you simply add "queue within traffic class" ID on top of this to get the "queue within pipe", which provides the lower bits of the "queue within port" that this function is looking to compute. Makes sense?
It would be good to do some more tests to trace the packet through different pipe traffic classes and queues.

I am afraid this is also incorrect, as although the mbuf->sched.traffic_class should be in sync with the traffic class built into the librte_sched hierarchy (and mbuf->sched.queue_id), there is no guarantee that:
1. The application is using and populating the mbuf->sched.traffic_class field
2. The application is assigning the same meaning or equivalence levels between the mbuf->sched.traffic_class and the librte_sched hierarchy traffic class.
We need to obtain the traffic class ID from queue ID, please. Thank you for your understanding!
There is also a quick way to do this as well through a similar small precomputed table: input = "queue within pipe" ID, outputs are traffic class ID and "queue within traffic class" ID. Makes sense?
We need to use this strategy for all the places in this file, so in this file we only use mbuf->sched.queue and not use mbuf->sched.traffic_class (nor its accessor function rte_mbuf_sched_traffic_class_get()) at all. This accessor function shows up 4 times currently.
