Description: Upon startup, the program will configure the EMAC/GMAC with a default IP and MAC address and then ask the transceiver to auto-negotiate the best mode of operation. Once this is done, it will start to monitor incoming packets and processing them whenever appropriate. The basic will only answer to two kinds of packets: - It will reply to ARP requests with its MAC address, - and to ICMP ECHO request so the device can be PING'ed.
