Transparent WiFi to Ethernet router/adapter

[tankist]

I need to build a transparent WiFi to Ethernet (and vise versa) router. The main using scenario is connect laptop via WiFi to access point of ESP32-S3 and get full illusion of direct connection to Ethernet.

I guess I need to capture IP packets from WiFi and redirect them into Ethernet adapter, but don't know how to get raw IP packets from lwIP stack. Another question how to connect Ethernet adapter to embedded lwIP stack simultaneously with WiFi.

Any idea how to do this?
