    So your original question as made wasn't really relevant then. You have hardware that you don't know if it is correct or broken, and you have thrown in software that you don't understand in it.

    Any code inside that board that is managing to make the board send something out, will result in packets that can be sniffed to know what MAC address that is used.

    If you understand the code, then you should be able to know how to get the board to try to send something (assuming the hardware is actually working).

    If you understand the code and hardware, then you should also be able to know if the code contains a hard-coded MAC address or if there is a MAC address stored in EEPROM or similar.

    So why did you make a post where the only fact you bothered to give was "LAN8720" when you could have mentioned what development board you based your own hardware on. Or what software packet you downloaded into your board?

    You often go into a car shop and demand to buy a spare part for your car, while refusing to tell them brand and model of car? You think that would be a working route to be able to actually get the correct spare part?
