29 | * DOC: Introduction | |
30 | * | |
31 | * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges | |
32 | * userspace and drivers, and offers some utility functionality associated | |
33 | * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used | |
34 | * by all modern wireless drivers in Linux, so that they offer a consistent | |
35 | * API through nl80211. For backward compatibility, cfg80211 also offers | |
36 | * wireless extensions to userspace, but hides them from drivers completely. | |
37 | * | |
38 | * Additionally, cfg80211 contains code to help enforce regulatory spectrum | |
39 | * use restrictions. | |

44 | * DOC: Device registration | |
45 | * | |
46 | * In order for a driver to use cfg80211, it must register the hardware device | |
47 | * with cfg80211. This happens through a number of hardware capability structs | |
48 | * described below. | |
49 | * | |
50 | * The fundamental structure for each device is the 'wiphy', of which each | |
51 | * instance describes a physical wireless device connected to the system. Each | |
52 | * such wiphy can have zero, one, or many virtual interfaces associated with | |
53 | * it, which need to be identified as such by pointing the network interface's | |
54 | * @ieee80211_ptr pointer to a &struct wireless_dev which further describes | |
55 | * the wireless part of the interface, normally this struct is embedded in the | |
56 | * network interface's private data area. Drivers can optionally allow creating | |
57 | * or destroying virtual interfaces on the fly, but without at least one or the | |
58 | * ability to create some the wireless device isn't useful. | |
59 | * | |
60 | * Each wiphy structure contains device capability information, and also has | |
61 | * a pointer to the various operations the driver offers. The definitions and | |
62 | * structures here describe these capabilities in detail. | |

630 | * be invoked with a scan definition. This scan definition contains the | |
631 | * channels to scan, and the SSIDs to send probe requests for (including the | |
632 | * wildcard, if desired). A passive scan is indicated by having no SSIDs to | |
633 | * probe. Additionally, a scan request may contain extra information elements | |

636 | * in the wiphy structure. | |
