+/* 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
