| 25 | * DOC: Introduction |
| 26 | * |
| 27 | * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges |
| 28 | * userspace and drivers, and offers some utility functionality associated |
| 29 | * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used |
| 30 | * by all modern wireless drivers in Linux, so that they offer a consistent |
| 31 | * API through nl80211. For backward compatibility, cfg80211 also offers |
| 32 | * wireless extensions to userspace, but hides them from drivers completely. |
| 33 | * |
| 34 | * Additionally, cfg80211 contains code to help enforce regulatory spectrum |
| 35 | * use restrictions. |

| 39 | /** |
| 40 | * DOC: Device registration |
| 41 | * |
| 42 | * In order for a driver to use cfg80211, it must register the hardware device |
| 43 | * with cfg80211. This happens through a number of hardware capability structs |
| 44 | * described below. |
| 45 | * |
| 46 | * The fundamental structure for each device is the 'wiphy', of which each |
| 47 | * instance describes a physical wireless device connected to the system. Each |
| 48 | * such wiphy can have zero, one, or many virtual interfaces associated with |
| 49 | * it, which need to be identified as such by pointing the network interface's |
| 50 | * @ieee80211_ptr pointer to a &struct wireless_dev which further describes |
| 51 | * the wireless part of the interface, normally this struct is embedded in the |
| 52 | * network interface's private data area. Drivers can optionally allow creating |
| 53 | * or destroying virtual interfaces on the fly, but without at least one or the |
| 54 | * ability to create some the wireless device isn't useful. |
| 55 | * |
| 56 | * Each wiphy structure contains device capability information, and also has |
| 57 | * a pointer to the various operations the driver offers. The definitions and |
| 58 | * structures here describe these capabilities in detail. |

| 869 | * |
| 870 | * The scanning process itself is fairly simple, but cfg80211 offers quite |
| 871 | * a bit of helper functionality. To start a scan, the scan operation will |
| 872 | * be invoked with a scan definition. This scan definition contains the |
| 873 | * channels to scan, and the SSIDs to send probe requests for (including the |
| 874 | * wildcard, if desired). A passive scan is indicated by having no SSIDs to |
| 875 | * probe. Additionally, a scan request may contain extra information elements |
| 876 | * that should be added to the probe request. The IEs are guaranteed to be |
| 877 | * well-formed, and will not exceed the maximum length the driver advertised |
| 878 | * in the wiphy structure. |
| 879 | * |
| 880 | * When scanning finds a BSS, cfg80211 needs to be notified of that, because |
| 881 | * it is responsible for maintaining the BSS list; the driver should not |
| 882 | * maintain a list itself. For this notification, various functions exist. |
| 883 | * |
| 884 | * Since drivers do not maintain a BSS list, there are also a number of |
| 885 | * functions to search for a BSS and obtain information about it from the |
| 886 | * BSS structure cfg80211 maintains. The BSS list is also made available |
| 887 | * to userspace. |
