Subject: [PATCH net-next v5 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 MT7996 driver in order to enable the offloading.
MT76 support has been posted as RFC in [0] in order to show how the
APIs are consumed.
