Add support for the IP101 chip to be able to use the Espressif Ethernet Kit. Based on this issue: #3554

PlatformIO latest version. I have the following compile error.

Platformio.ini
[env:esp-wrover-kit]
platform = espressif32
board = esp-wrover-kit
framework = arduino

monitor_speed = 115200

What does this have to do with IP101 support? There is a button for new issues on the issues page.

Everything! I do have a ESP32-Ethernet-kit v1.1 with IP101 chip and try to compile in platformIo and a compile error is comming up.

This looks to be an error inside ArduinoOTA. This pull was just a small change to ETH.cpp and ETH.h

OK thanks. Everything is working fine now.
What I dit not know is PlatforIO is using a directory "framework-arduinoespressif32", containing "arduino-esp32". That's why I whos working with an older version.
