+RARP EXAMPLE
+
+Description:
+In this example, it will send rarp request for 3 times. And the rarp reply callback will print the received reply IP address.
+
+Configuration:
+[platform_opts.h]
+    #define CONFIG_EXAMPLE_RARP    1
+	
+Execution:
+You need to connect to WiFi manually by AT command. After connected the rarp request will be sent.
+
+RARP server:
+For Ubuntu, you can try to setup the RARP server as doing this:
+<EFBFBD>	apt-get install rarpd
+<EFBFBD>	touch /etc/ethers
+<EFBFBD>	add <20>00:e0:4c:87:xx:xx(Ameba<62>s MAC)        client<6E>  in /etc/ethers
+<EFBFBD>	add<64>192.168.1.xx(Ameba<62>s ip)               client<6E>  in /etc/hosts
+
