  26 /* This driver supports wwan (3G/LTE/?) devices using a vendor
  27  * specific management protocol called Qualcomm MSM Interface (QMI) -
  28  * in addition to the more common AT commands over serial interface
  29  * management
  30  *
  31  * QMI is wrapped in CDC, using CDC encapsulated commands on the
  32  * control ("master") interface of a two-interface CDC Union
  33  * resembling standard CDC ECM.  The devices do not use the control
  34  * interface for any other CDC messages.  Most likely because the
  35  * management protocol is used in place of the standard CDC
  36  * notifications NOTIFY_NETWORK_CONNECTION and NOTIFY_SPEED_CHANGE
  37  *
  38  * Alternatively, control and data functions can be combined in a
  39  * single USB interface.
  40  *
  41  * Handling a protocol like QMI is out of the scope for any driver.
  42  * It is exported as a character device using the cdc-wdm driver as
  43  * a subdriver, enabling userspace applications ("modem managers") to
  44  * handle it.
  45  *
  46  * These devices may alternatively/additionally be configured using AT
  47  * commands on a serial interface
