David Smart / EthernetInterface

FUNCTIONAL Update from mbed v49: Add APIs for setName/getName so device is name addressible. Also APIs for getting link stats. Also, minor derivative to reduce compiler warnings and tag read-only parameters as const.

Dependencies:   Socket lwip-eth lwip-sys lwip

Dependents:   WattEye X10Svr SSDP_Server
