// For ESP32, the remaining five pins are at least somewhat configurable.
// eth_address  is in range [0..31], indicates which PHY (MAC?) address should be allocated to the interface
// eth_power    is an output GPIO pin used to enable/disable the ethernet port (and/or external oscillator)
// eth_mdc      is an output GPIO pin used to provide the clock for the management data
// eth_mdio     is an input/output GPIO pin used to transfer management data
// eth_type     is the physical ethernet module's type (ETH_PHY_LAN8720, ETH_PHY_TLK110)
// eth_clk_mode defines the GPIO pin and GPIO mode for the clock signal
//              However, there are really only four configurable options on ESP32:
//              ETH_CLOCK_GPIO0_IN    == External oscillator, clock input  via GPIO0
//              ETH_CLOCK_GPIO0_OUT   == ESP32 provides 50MHz clock output via GPIO0
//              ETH_CLOCK_GPIO16_OUT  == ESP32 provides 50MHz clock output via GPIO16
//              ETH_CLOCK_GPIO17_OUT  == ESP32 provides 50MHz clock output via GPIO17
