This diagram explains how oFono and ConnMan are interacting to handle a data
call from a DUN client.
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, ...).
