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
