Use this function to recover a device not on your subnet. This function is designed to re-enable DHCP on a device that has been removed from your subnet by a SetIPAddress command. Since you can no longer send commands to a device that is no longer on your subnet, it is helpful to be able to re-enable DHCP so that you may once again. NOTE: This function requires use of the MAC address and is therefore a privileged (RAW Socket) function. You may alternatively hard code the device's MAC address into the ceth_device struct provided to this function.
