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