This patch is needed because NPU firmware binaries are board specific since they depend on the MediaTek WiFi chip used on the board (e.g. MT7996 or MT7992) and the WiFi chip version info is not available in the NPU driver. This is a preliminary patch to enable MT76 NPU offloading if the Airoha SoC is equipped with MT7996 (Eagle) WiFi chipset.
