Cover letter [RFC mt76 v2 0/4] Add NPU offload support to MT7996 driver
Introduce Airoha NPU support to MT7996 driver. NPU is used to enable traffic forward offloading between the MT76 NIC and Airoha ethernet one available on the Airoha EN7581 SoC using Netfilter Flowtable APIs. This series is based on the following net-next series for airoha_npu driver:

Changes in RFCv2:
- Do not compile MT76 NPU codebase if NPU support is disabled in airoha-eth driver.
- Remove dev_warn() in mt7996_pci_probe() if NPU support is disabled.
