| 26 | * DOC: Introduction |
| 27 | * |
| 28 | * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges |
| 29 | * userspace and drivers, and offers some utility functionality associated |
| 30 | * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used |
| 31 | * by all modern wireless drivers in Linux, so that they offer a consistent |
| 32 | * API through nl80211. For backward compatibility, cfg80211 also offers |
| 33 | * wireless extensions to userspace, but hides them from drivers completely. |
| 34 | * |
| 35 | * Additionally, cfg80211 contains code to help enforce regulatory spectrum |
| 36 | * use restrictions. |

| 40 | /** |
| 41 | * DOC: Device registration |
| 42 | * |
| 43 | * In order for a driver to use cfg80211, it must register the hardware device |
| 44 | * with cfg80211. This happens through a number of hardware capability structs |
| 45 | * described below. |
| 46 | * |
| 47 | * The fundamental structure for each device is the 'wiphy', of which each |
| 48 | * instance describes a physical wireless device connected to the system. Each |
| 49 | * such wiphy can have zero, one, or many virtual interfaces associated with |
| 50 | * it, which need to be identified as such by pointing the network interface's |
| 51 | * @ieee80211_ptr pointer to a &struct wireless_dev which further describes |
| 52 | * the wireless part of the interface, normally this struct is embedded in the |
| 53 | * network interface's private data area. Drivers can optionally allow creating |
| 54 | * or destroying virtual interfaces on the fly, but without at least one or the |
| 55 | * ability to create some the wireless device isn't useful. |
| 56 | * |
| 57 | * Each wiphy structure contains device capability information, and also has |
| 58 | * a pointer to the various operations the driver offers. The definitions and |
| 59 | * structures here describe these capabilities in detail. |

| 290 | * Each wireless device and each virtual interface offer a set of configuration |
| 291 | * operations and other actions that are invoked by userspace. Each of these |
| 292 | * actions is described in the operations structure, and the parameters these |
| 293 | * operations use are described separately. |
| 294 | * |
| 295 | * Additionally, some operations are asynchronous and expect to get status |
| 296 | * information via some functions that drivers need to call. |
| 297 | * |
| 298 | * Scanning and BSS list handling with its associated functionality is described |
| 299 | * in a separate chapter. |

| 1164 | * |
| 1165 | * The scanning process itself is fairly simple, but cfg80211 offers quite |
| 1166 | * a bit of helper functionality. To start a scan, the scan operation will |
| 1167 | * be invoked with a scan definition. This scan definition contains the |
| 1168 | * channels to scan, and the SSIDs to send probe requests for (including the |
| 1169 | * wildcard, if desired). A passive scan is indicated by having no SSIDs to |
| 1170 | * probe. Additionally, a scan request may contain extra information elements |
| 1171 | * that should be added to the probe request. The IEs are guaranteed to be |
| 1172 | * well-formed, and will not exceed the maximum length the driver advertised |
| 1173 | * in the wiphy structure. |
| 1174 | * |
| 1175 | * When scanning finds a BSS, cfg80211 needs to be notified of that, because |
| 1176 | * it is responsible for maintaining the BSS list; the driver should not |
| 1177 | * maintain a list itself. For this notification, various functions exist. |
| 1178 | * |
| 1179 | * Since drivers do not maintain a BSS list, there are also a number of |
| 1180 | * functions to search for a BSS and obtain information about it from the |
| 1181 | * BSS structure cfg80211 maintains. The BSS list is also made available |
| 1182 | * to userspace. |

| 1937 | * Parameters include ACL policy, an array of MAC address of stations |
| 1938 | * and the number of MAC addresses. If there is already a list in driver |
| 1939 | * this new list replaces the existing one. Driver has to clear its ACL |
| 1940 | * when number of MAC addresses entries is passed as 0. Drivers which |
| 1941 | * advertise the support for MAC based ACL have to implement this callback. |
