/* 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 |

/* Make up an ethernet header if the packet doesn't have one. |

|
* A firmware bug common among several devices cause them to send raw |
|
* IP packets under some circumstances. There is no way for the |
|
* driver/host to know when this will happen. And even when the bug |
|
* hits, some packets will still arrive with an intact header. |
|
* |
|
* The supported devices are only capably of sending IPv4, IPv6 and |
|
* ARP packets on a point-to-point link. Any packet with an ethernet |
|
* header will have either our address or a broadcast/multicast |
|
* address as destination. ARP packets will always have a header. |
|
* |
|
* This means that this function will reliably add the appropriate |
|
* header iff necessary, provided our hardware address does not start |
|
* with 4 or 6. |
|
* |
|
* Another common firmware bug results in all packets being addressed |
|
* to 00:a0:c6:00:00:00 despite the host address being different. |
|
* This function will also fixup such packets. |
