21/*
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 * Handling a protocol like QMI is out of the scope for any driver.
35 * It can be exported as a character device using the cdc-wdm driver,
36 * which will enable userspace applications ("modem managers") to
37 * handle it. This may be required to use the network interface
38 * provided by the driver.
39 *
40 * These devices may alternatively/additionally be configured using AT
41 * commands on any of the serial interfaces driven by the option driver
42 *
43 * This driver binds only to the data ("slave") interface to enable
44 * the cdc-wdm driver to bind to the control interface. It still
45 * parses the CDC functional descriptors on the control interface to
46 * a) verify that this is indeed a handled interface (CDC Union
47 * header lists it as slave)
48 * b) get MAC address and other ethernet config from the CDC Ethernet
49 * header
50 * c) enable user bind requests against the control interface, which
51 * is the common way to bind to CDC Ethernet Control Model type
52 * interfaces
53 * d) provide a hint to the user about which interface is the
54 * corresponding management interface
