KC868-A6 with waveshare LAN8720

[llast]

Hello,

I am trying to setup KC868-A6 with LAN using waveshare lan8720 controller - I used the following configuration:

```ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  phy_addr: 0
```
but I keep on getting the folowing error on esphome:
[11:11:41][C][ethernet:041]: Setting up Ethernet...
[11:11:41][V][esp-idf:000]: E (1589) esp.emac: emac_esp32_init(371): reset timeout
[11:11:41]
[11:11:41][V][esp-idf:000]: E (1589) esp_eth: esp_eth_driver_install(228): init mac failed

would you be able to support this configuration?

KC868-A6 not have free GPIO for ethernet chip.

is it possible to use the pins allocated for LORA / SPI?

maybe can't , ethernet pin can use by any ESP32 pins. Only some special pins can be used.
