Board.txt changes
Add the following line to your board.txt file so the firmware knows which module you’re using
wifi.moduleType = esp32eth
Usage
To activate the ethernet connection when connected to WiFi already, send as a macro
M552 S-1
M552 S1 p"ethernet"
If you always want to use ethernet, replace the line M552 S1 with M552 S1 p"ethernet".
