The Nexus 7 comes with an Infineon modem, which ModemManager doesn't
properly handle. Once connected, the modem requires some tunneling of
the raw IP data through the serial device.

Work is started, but not yet finished, in the "aleksander/infineon-
rawip" branch in upstream git.

Bug description:
  Repeated attempts to get 3G connectivity on my Nexus 7 fail. The same
  SIM worked fine under Android.

  Very occasionally, a notification pops up saying that I have
  connected, but I am then immediately disconnected again. Most of the
  time, though, I get a 'disconnected' notification and nothing else.

  My provider is giffgaff (UK). The mobile broadband hardware is
  definitely detected by Ubuntu, given that it appears in the network

  I can do further testing if asked.
