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

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

1390 | * be invoked with a scan definition. This scan definition contains the | |
1391 | * channels to scan, and the SSIDs to send probe requests for (including the | |
1392 | * wildcard, if desired). A passive scan is indicated by having no SSIDs to | |
1393 | * probe. Additionally, a scan request may contain extra information elements | |
1394 | * that should be added to the probe request. The IEs are guaranteed to be | |
1395 | * well-formed, and will not exceed the maximum length the driver advertised | |
1396 | * in the wiphy structure. | |
1397 | * | |
1398 | * When scanning finds a BSS, cfg80211 needs to be notified of that, because | |
1399 | * it is responsible for maintaining the BSS list; the driver should not | |
1400 | * maintain a list itself. For this notification, various functions exist. | |
1401 | * | |
1402 | * Since drivers do not maintain a BSS list, there are also a number of | |
1403 | * functions to search for a BSS and obtain information about it from the | |
1404 | * BSS structure cfg80211 maintains. The BSS list is also made available | |

2488 | * when number of MAC addresses entries is passed as 0. Drivers which | |
2489 | * advertise the support for MAC based ACL have to implement this callback. | |
04f39047 SW |

2491 | * @start_radar_detection: Start radar detection in the driver. | |
8bf24293 JM |
2492 | * |
2493 | * @update_ft_ies: Provide updated Fast BSS Transition information to the | |
2494 | * driver. If the SME is in the driver/firmware, this information can be | |
2495 | * used in building Authentication and Reassociation Request frames. | |
5de17984 AS |
2496 | * |
2497 | * @crit_proto_start: Indicates a critical protocol needs more link reliability | |
2498 | * for a given duration (milliseconds). The protocol is provided so the | |
2499 | * driver can take the most appropriate actions. | |
2500 | * @crit_proto_stop: Indicates critical protocol no longer needs increased link | |
2501 | * reliability. This operation can not fail. | |
be29b99a | 2502 | * @set_coalesce: Set coalesce parameters. |
16ef1fe2 | 2503 | * |
97dc94f1 MK |
2504 | * @channel_switch: initiate channel-switch procedure (with CSA). Driver is |
2505 | * responsible for veryfing if the switch is possible. Since this is | |
2506 | * inherently tricky driver may decide to disconnect an interface later | |
2507 | * with cfg80211_stop_iface(). This doesn't mean driver can accept | |
2508 | * everything. It should do it's best to verify requests and reject them | |
2509 | * as soon as possible. | |
fa9ffc74 KP |
2510 | * |
2511 | * @set_qos_map: Set QoS mapping information to the driver | |
e16821bc JM |
2512 | * |
2513 | * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the | |
2514 | * given interface This is used e.g. for dynamic HT 20/40 MHz channel width | |
2515 | * changes during the lifetime of the BSS. | |
960d01ac JB |
2516 | * |
2517 | * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device | |
2518 | * with the given parameters; action frame exchange has been handled by | |
2519 | * userspace so this just has to modify the TX path to take the TS into | |
2520 | * account. | |
2521 | * If the admitted time is 0 just validate the parameters to make sure | |
2522 | * the session can be created at all; it is valid to just always return | |
2523 | * success for that but that may result in inefficient behaviour (handshake | |
2524 | * with the peer followed by immediate teardown when the addition is later | |
2525 | * rejected) | |
2526 | * @del_tx_ts: remove an existing TX TS | |
6e0bd6c3 RL |
2527 | * |
2528 | * @join_ocb: join the OCB network with the specified parameters | |
2529 | * (invoked with the wireless_dev mutex held) | |
2530 | * @leave_ocb: leave the current OCB network | |
2531 | * (invoked with the wireless_dev mutex held) | |
1057d35e AN |
2532 | * |
2533 | * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver | |
2534 | * is responsible for continually initiating channel-switching operations | |
2535 | * and returning to the base channel for communication with the AP. | |
2536 | * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both | |
2537 | * peers must be on the base channel when the call completes. | |
