+The usrp2 recovery app:
+
+When the usrp2 has an unknown or bad ip address in its eeprom,
+it may not be possible to communicate with the usrp2 over ip/udp.
+
+This app will send a raw ethernet packet to bypass the ip layer.
+The packet will contain a known ip address to burn into eeprom.
+Because the recovery packet is sent with a broadcast mac address,
+only one usrp2 should be present on the interface upon execution.
+
+This app requires super-user privileges and only works on linux.
