ESP32 OTA over Ethernet. Typically for an ESP32 feather with an Ethernet featherwing. Modification of ESP Arduino BSP OTA to break free of Wifi dependencies to support Ethernet. Tested on Adafruit ESP32 Feather with Featherwing Ethernet board. Uses https://github.com/TrippyLighting/EthernetBonjour for mDNS.
When time allows this should be a part of https://github.com/espressif/arduino-esp32.
