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