Merge branch 'octeon-drr-config'

Sunil Goutham says:

====================
cn10k: DWRR MTU and weights configuration

On OcteonTx2 DWRR quantum is directly configured into each of
the transmit scheduler queues. And PF/VF drivers were free to
config any value upto 2^24.

On CN10K, HW is modified, the quantum configuration at scheduler
queues is in terms of weight. And SW needs to setup a base DWRR MTU
at NIX_AF_DWRR_RPM_MTU / NIX_AF_DWRR_SDP_MTU. HW will do
'DWRR MTU * weight' to get the quantum.

This patch series addresses this HW change on CN10K silicons,
both admin function and PF/VF drivers are modified.

Also added support to program DWRR MTU via devlink params.
