230718bd | 25 | /* This driver supports wwan (3G/LTE/?) devices using a vendor |
423ce8ca BM |
26 | * specific management protocol called Qualcomm MSM Interface (QMI) - |
27 | * in addition to the more common AT commands over serial interface | |
28 | * management | |
29 | * | |
30 | * QMI is wrapped in CDC, using CDC encapsulated commands on the | |
31 | * control ("master") interface of a two-interface CDC Union | |
32 | * resembling standard CDC ECM. The devices do not use the control | |
33 | * interface for any other CDC messages. Most likely because the | |
34 | * management protocol is used in place of the standard CDC | |
35 | * notifications NOTIFY_NETWORK_CONNECTION and NOTIFY_SPEED_CHANGE | |
36 | * | |
230718bd BM |
37 | * Alternatively, control and data functions can be combined in a |
38 | * single USB interface. | |
39 | * | |
423ce8ca | 40 | * Handling a protocol like QMI is out of the scope for any driver. |
230718bd BM |
41 | * It is exported as a character device using the cdc-wdm driver as |
42 | * a subdriver, enabling userspace applications ("modem managers") to | |
43 | * handle it. | |
423ce8ca BM |
44 | * |
45 | * These devices may alternatively/additionally be configured using AT | |
230718bd | 46 | * commands on a serial interface |

158 | * A firmware bug common among several devices cause them to send raw | |
159 | * IP packets under some circumstances. There is no way for the | |
160 | * driver/host to know when this will happen. And even when the bug | |

165 | * header will have either our address or a broadcast/multicast | |
166 | * address as destination. ARP packets will always have a header. | |
167 | * | |
168 | * This means that this function will reliably add the appropriate | |
169 | * header iff necessary, provided our hardware address does not start | |
170 | * with 4 or 6. | |

173 | * to 00:a0:c6:00:00:00 despite the host address being different. | |
174 | * This function will also fixup such packets. | |
