// Need this override function on non-mbed hardware to provide the MAC address.
//
// The mbed Ethernet library sets the MAC address by calling a weak function
// extern "C" void mbed_mac_address(char * mac) to copy in a 6 Byte (12 character) MAC address.
// This function performs a semihosting request to the mbed interface to get the serial number,
// which contains a MAC address unique to every mbed device.
// If you are using the eth library on your own board (i.e. not an mbed board),
// you should implement your own extern "C" void mbed_mac_address(char * mac) function
// to overwrite the existing one and avoid a call to the interface (which doesnt exist).
