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

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

1366 | * The scanning process itself is fairly simple, but cfg80211 offers quite | |
1367 | * a bit of helper functionality. To start a scan, the scan operation will | |
1368 | * be invoked with a scan definition. This scan definition contains the | |
1369 | * channels to scan, and the SSIDs to send probe requests for (including the | |
1370 | * wildcard, if desired). A passive scan is indicated by having no SSIDs to | |
1371 | * probe. Additionally, a scan request may contain extra information elements | |
1372 | * that should be added to the probe request. The IEs are guaranteed to be | |
1373 | * well-formed, and will not exceed the maximum length the driver advertised | |
1374 | * in the wiphy structure. | |
1375 | * | |
1376 | * When scanning finds a BSS, cfg80211 needs to be notified of that, because | |
1377 | * it is responsible for maintaining the BSS list; the driver should not | |
1378 | * maintain a list itself. For this notification, various functions exist. | |
1379 | * | |
1380 | * Since drivers do not maintain a BSS list, there are also a number of | |
1381 | * functions to search for a BSS and obtain information about it from the | |
1382 | * BSS structure cfg80211 maintains. The BSS list is also made available | |

2367 | * this new list replaces the existing one. Driver has to clear its ACL | |

2384 | * @channel_switch: initiate channel-switch procedure (with CSA). Driver is |
2385 | * responsible for veryfing if the switch is possible. Since this is | |
2386 | * inherently tricky driver may decide to disconnect an interface later | |
2387 | * with cfg80211_stop_iface(). This doesn't mean driver can accept | |

2398 | * with the given parameters; action frame exchange has been handled by | |
2399 | * userspace so this just has to modify the TX path to take the TS into | |
2400 | * account. | |
2401 | * If the admitted time is 0 just validate the parameters to make sure | |
2402 | * the session can be created at all; it is valid to just always return | |
2403 | * success for that but that may result in inefficient behaviour (handshake | |
2404 | * with the peer followed by immediate teardown when the addition is later | |
2405 | * rejected) | |

6e0bd6c3 RL |
