The Ethernet is handled by Microchip's 10BASE-T/100BASE-TX transceiver LAN8710A. The
board is equipped with standard RJ45 connector.
The RJ45 connector has two LEDs. The green indicates whether a proper 100Mb Ethernet
connection is established and the yellow LED indicates whether there is activity on the port.
