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