This function broadcasts a request for all devices to identify themselves. A udp broadcast is sent out on a special port that SeaIO devices will answer to responding with a package of device specific information including IP, NetMask, Gateway, and DHCP Name. This function will then attempt to retrieve all the MAC addresses for the found devices. Retrieving the MAC Addresses is a privileged operation and will gracefully fail reporting a MAC of 00:00:00:00:00:00.
