Subject: [PATCH] cdc_ether: flag the Cinterion AHS8 modem by gemalto as WWAN

    The Cinterion AHS8 is a 3G device with one embedded WWAN interface
    using cdc_ether as a driver.

    The modem is  controlled via AT commands through the exposed TTYs.

    AT+CGDCONT write command can be used to activate or deactivate a WWAN
    connection for a PDP context defined with the same command. UE supports
    one WWAN adapter.
