Of cource MTU will be 14 bytes less than original (because of additional "fake" ETH head...

Hello. I need to build esp32-based transparent WiFi bridge like that: Copper ETH <-> ESP32 AP <-> ESP32 STA <-> Copper ETH So, first part Copper ETH <-> ESP32 AP works well (based on "eth2ap" example) Second part ESP32 STA <-> Copper ETH (based on the same "eth2ap" example, but modified to STA) has ...
