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

  octeontx2-pf: implement transmit schedular allocation algorithm
  sch_htb: Allow HTB quantum parameter in offload mode
  octeontx2-pf: htb offload support for Round Robin scheduling

Please extend the driver documentation appropriately, there's 
a "Setup HTB offload" section which only shows strict prio now.

Thanks for the review. Will add the changes in the next version.

Thanks,
