ESP32 Ethernet netdev interface

ESP32 ethernet network device driver.

This module realizes a netdev interface using the ESP32 Ethernet MAC module.

ESP32 provides an Ethernet MAC layer module (EMAC) according to the IEEE 802.3 standard which can be used together with an external physical layer chip (PHY) to realize a 100/10 Mbps Ethernet interface. Supported PHY chips are the Microchip LAN8710/LAN8720 and the Texas Instruments TLK110.

The RIOT port for ESP32 realizes with module esp_eth a netdev driver for the EMAC which uses RIOT’s standard Ethernet interface.

If the board has one of the supported PHY layer chips connected to the ESP32, the esp_eth module should be enabled by default in board’s Makefile.dep when module netdev_default is used.

ifneq (,$(filter netdev_default gnrc_netdev_default,$(USEMODULE)))
    USEMODULE += esp_eth
endif
Otherwise, the application has to add the esp_eth module in its makefile when needed.

Note

The board has to have one of the supported PHY modules to be able to use the Ethernet MAC module.
