Subject: [net-next PatchV4 0/4] octeontx2-pf: support Round Robin scheduling

octeontx2 and CN10K silicons support Round Robin scheduling. When multiple
traffic flows reach transmit level with the same priority, with Round Robin
scheduling traffic flow with the highest quantum value is picked. With this
support, the user can add multiple classes with the same priority and
different quantum in htb offload.

This series of patches adds support for the same.

Patch1: implement transmit schedular allocation algorithm as preparation
        for support round robin scheduling.

Patch2: Allow quantum parameter in HTB offload mode.

Patch3: extends octeontx2 htb offload support for Round Robin scheduling

Patch4: extend QOS documentation for Round Robin scheduling

---
v4 * update classid values in documentation.

v3 * 1. update QOS documentation for round robin scheduling
     2. added out of bound checks for quantum parameter

v2 * change data type of otx2_index_used to reduce size of structure
     otx2_qos_cfg
