I tried uncommenting the DISABLE_ESPNOW, doesn't help

env:

[env:esp32_eth_V4]
board = esp32-poe
platform = ${esp32_idf_V4.platform}
build_unflags = ${common.build_unflags}
build_flags = ${common.build_flags} ${esp32_idf_V4.build_flags} -D WLED_RELEASE_NAME=\"ESP32_Ethernet\" -D RLYPIN=-1 -D WLED_USE_ETHERNET -D BTNPIN=-1
  -D WLED_DISABLE_ESPNOW ;; ESP-NOW requires wifi, may crash with ethernet only
  ${esp32.AR_build_flags}
lib_deps = ${esp32_idf_V4.lib_deps}
  ${esp32.AR_lib_deps}
board_build.partitions = ${esp32.default_partitions}
board_build.flash_mode = dio
upload_speed = 921600

Everything's fine until the ethernet type is selected, WT32-ETH01 in my case. Once done it'll hang whether a cable is connected or not and I have to wipe config to get it back.

@netmindz IDF v4.0.0 and up uses ARDUINO_EVENT_ instead of SYSTEM_EVENT_

This PR should fix it up...

#4526

Some crazy issues getting this to work which seem to be down to an older Tasmota version.

Use this Tasmota build which is based on IDF 4.4.6:

✅ https://github.com/tasmota/platform-espressif32/releases/download/2023.10.04/platform-espressif32.zip

Do not use this build, which is based on IDF 4.4.4:

❌ https://github.com/tasmota/platform-espressif32/releases/download/2023.06.02/platform-espressif32.zip

Tested with connecting and disconnecting Ethernet, boots correctly with Ethernet, fails back and forth successfully.

I had to add a secondary WiFi.disconnect(true); as it seems the WiFi events aren't reliable on bootup or something else is overriding connectivity things.
