> Implement the offload of the tc mqprio hw queue priority in the stmmac
> driver. This feature requires the mqprio to be configured in channel
> mode.
> Do not overwrite real_num_tx_queues configured by the qdisc in
> stmmac_hw_setup().
> 
> ---
> Changes in v2:
> - Forbid cbs queue offload if mqprio is already enabled.
> - SP requires 1:1 TC to TXQ map.
> - Fix the real_num_tx_queue overwrite during device open.
> - Require the qdisc to be configured in channel mode to enable hw queue
>   priority offload in order to not introduce any regression in the
>   previous driver behaviour.
> - Link to v1: https://lore.kernel.org/r/20260918-stmmac-mqprio-prio-offload-v1-1-5328157fcb58@oss.qualcomm.com
