[PATCH net-next v3 0/3] Implement mqprio and ets qdisc offload in stmmac driver

[Lorenzo Bianconi]

---
Changes in v3:
- Limit number of tx queues to ETS bands enabling ETS qdisc offload.
- Do not overwrite previosuly configured qdisc if ETS offloading fails.
- Check dcb DMA capability before programming the sched registers.
- Always power-on the device before applying qdisc offload configuration
- Fix priority applied for SP tx queues.
- Link to v2: https://lore.kernel.org/r/20260807-stmmac-ets-offload-v2-0-9ac67af92cb8@oss.qualcomm.com

Changes in v2:
- Implement strict priority policy in mqprio qdisc offload
- Restore to dt configured values destroying the qdisc
- Do not ets offload if there are any queues in avb mode.
- Re-apply ETS configuration closing/opening the net_device.
- Link to v1: https://lore.kernel.org/r/20260804-stmmac-ets-offload-v1-1-f3a09169d22b@oss.qualcomm.com
