 1) GAtServer receive ATD*99#.
 2) The GAtPPP server is setup.
 3) oFono through GAtPPP notify ConnMan that he needs a TUN/TAP interface.
 4) oFono is notified that TUN/TAP interface is created and can start exchanging
-PPP packets with DUN client. Those PPP packets are converted into IP stream
-and transmitted to/received from TUN/TAP interface.
-5) ConnMan is selecting which interface to send IP packets (WiFi, 3G, ethX, ...).
