+ Support WWAN LTE/3G devices based on Qualcomm Mobile Data Modem
+ (MDM) chipsets. Examples of such devices are
+ * Huawei E392/E398
+
+ This driver will only drive the ethernet part of the chips.
+ The devices require additional configuration to be usable.
+ Multiple management interfaces with linux drivers are
+ available:
+
+ * option: AT commands on /dev/ttyUSBx
+ * cdc-wdm: Qualcomm MSM Interface (QMI) protocol on /dev/cdc-wdmx
+
+ A modem manager with support for QMI is recommended.

+ * 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
+ *
+ * Handling a protocol like QMI is out of the scope for any driver.
+ * It can be exported as a character device using the cdc-wdm driver,
+ * which will enable userspace applications ("modem managers") to
+ * handle it. This may be required to use the network interface
+ * provided by the driver.
+ *
+ * These devices may alternatively/additionally be configured using AT
+ * commands on any of the serial interfaces driven by the option driver
+ *
+ * This driver binds only to the data ("slave") interface to enable
+ * the cdc-wdm driver to bind to the control interface. It still
+ * parses the CDC functional descriptors on the control interface to
+ * a) verify that this is indeed a handled interface (CDC Union
+ * header lists it as slave)
+ * b) get MAC address and other ethernet config from the CDC Ethernet
+ * header
+ * c) enable user bind requests against the control interface, which
+ * is the common way to bind to CDC Ethernet Control Model type
+ * interfaces
+ * d) provide a hint to the user about which interface is the
+ * corresponding management interface
