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 | |
