warnings from Eth

[lbernstone]

Hardware:

Board: ESP32-C3 devkit
Core Installation version: master 22/10/2021
IDE name: Arduino IDE
Computer OS: Ubuntu

Description:

Warnings from Ethernet components in WiFi.
This does not prevent compilation. I don't know if it prevents Eth from working, and don't have the stuff to test. Just wanted to get eyes on this before v2.0.1 goes out the door.

Sketch: (leave the backquotes for code formatting)

#include <Arduino.h>
#include <WiFi.h>

void setup() {
}

void loop() {
}

Thanks @lbernstone
It won't prevent ETH from working.
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/network/esp_eth.html#_CPPv428esp_eth_set_default_handlersPv

It just needs to be removed from ETH.cpp. It's not needed in latest IDF 4.4 anymore.
I'll get it done.
