The eth_*() interface will be implemented by the UC_ETH class
This is currently implemented in net/eth.c
Look in include/net.h for details.

+ You must select Y to enable any network device support

+ This driver simply responds with fake ARP replies and ping
+ replies that are used to verify network stack functionality
+
+ This driver is particularly useful in the test/dm/eth.c tests
