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.
38 * Additionally, cfg80211 contains code to help enforce regulatory spectrum
44 * DOC: Device registration
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
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.
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.

1179 * @del_pmksa: Delete a cached PMKID.
1180 * @flush_pmksa: Flush all cached PMKIDs.

2438 * DOC: RFkill integration
2440 * RFkill integration in cfg80211 is almost invisible to drivers,
2441 * as cfg80211 automatically registers an rfkill instance for each
2442 * wireless device it knows about. Soft kill is also translated
2443 * into disconnecting and turning all interfaces off, drivers are
2444 * expected to turn off the device when all interfaces are down.
2446 * However, devices may have a hard RFkill line, in which case they
2447 * also need to interact with the rfkill subsystem, via cfg80211.
2448 * They can do this with a few helper functions documented here.
2452 * wiphy_rfkill_set_hw_state - notify cfg80211 about hw block state
2454 * @blocked: block status
2456 void wiphy_rfkill_set_hw_state(struct wiphy *wiphy, bool blocked);
2459 * wiphy_rfkill_start_polling - start polling rfkill
2462 void wiphy_rfkill_start_polling(struct wiphy *wiphy);
2465 * wiphy_rfkill_stop_polling - stop polling rfkill
2468 void wiphy_rfkill_stop_polling(struct wiphy *wiphy);
2470 #ifdef CONFIG_NL80211_TESTMODE
2474 * Test mode is a set of utility functions to allow drivers to
2475 * interact with driver-specific tools to aid, for instance,
2476 * factory programming.
2478 * This chapter describes how drivers interact with it, for more
2479 * information see the nl80211 book's chapter on it.
2483 * cfg80211_testmode_alloc_reply_skb - allocate testmode reply
2485 * @approxlen: an upper bound of the length of the data that will
2486 * be put into the skb
2488 * This function allocates and pre-fills an skb for a reply to
2489 * the testmode command. Since it is intended for a reply, calling
2490 * it outside of the @testmode_cmd operation is invalid.
2492 * The returned skb (or %NULL if any errors happen) is pre-filled
2493 * with the wiphy index and set up in a way that any data that is
2494 * put into the skb (with skb_put(), nla_put() or similar) will end
2495 * up being within the %NL80211_ATTR_TESTDATA attribute, so all that
2496 * needs to be done with the skb is adding data for the corresponding
2497 * userspace tool which can then read that data out of the testdata
2498 * attribute. You must not modify the skb in any other way.
2500 * When done, call cfg80211_testmode_reply() with the skb and return
2501 * its error code as the result of the @testmode_cmd operation.
2503 struct sk_buff *cfg80211_testmode_alloc_reply_skb(struct wiphy *wiphy,
2507 * cfg80211_testmode_reply - send the reply skb
2508 * @skb: The skb, must have been allocated with
2509 * cfg80211_testmode_alloc_reply_skb()
2511 * Returns an error code or 0 on success, since calling this
2512 * function will usually be the last thing before returning
2513 * from the @testmode_cmd you should return the error code.
2514 * Note that this function consumes the skb regardless of the
2517 int cfg80211_testmode_reply(struct sk_buff *skb);
2520 * cfg80211_testmode_alloc_event_skb - allocate testmode event
2522 * @approxlen: an upper bound of the length of the data that will
2523 * be put into the skb
2524 * @gfp: allocation flags
2526 * This function allocates and pre-fills an skb for an event on the
2527 * testmode multicast group.
2529 * The returned skb (or %NULL if any errors happen) is set up in the
2530 * same way as with cfg80211_testmode_alloc_reply_skb() but prepared
2531 * for an event. As there, you should simply add data to it that will
2532 * then end up in the %NL80211_ATTR_TESTDATA attribute. Again, you must
2533 * not modify the skb in any other way.
2535 * When done filling the skb, call cfg80211_testmode_event() with the
2536 * skb to send the event.
