[人鱼情未了]

Missing feature

ESP32 LAN8720 cannot be used
ESP32 Lan8270a normal use

-- Initialize ESP32-GATEWAY
eth.init({phy  = eth.PHY_LAN8720,
          addr = 0,
          clock_mode = eth.CLOCK_GPIO17_OUT,
          power = 5,
          mdc   = 23,
          mdio  = 18})

-- Initialize wESP32
eth.init({phy  = eth.PHY_LAN8720,
          addr = 0,
          clock_mode = eth.CLOCK_GPIO0_IN,
          mdc   = 16,
          mdio  = 17})

Justification

LAN8720 Half the price

Workarounds

Rebuild eth.c
