Subject: [PATCH net-next v2 0/7] net: airoha: Introduce NPU callbacks for
 wlan offloading

Similar to wired traffic, EN7581 SoC allows to offload traffic to/from
the MT76 wireless NIC configuring the NPU module via the Netfilter
flowtable. This series introduces the necessary NPU callback used by
the MT76 driver in order to enable the offloading.
Subsequent patches will introduce the required MT76 support.

---
Changes in v2:
- Introduce binding for memory regions used for wlan offload
- Rely on of_reserved_mem_region_to_resource_byname
- Export just wlan_{send,get}_msg NPU callback for MT76
- Improve commit messages
- Link to v1: https://lore.kernel.org/r/20250702-airoha-en7581-wlan-offlaod-v1-0-803009700b38@kernel.org
