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.

42/**
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.

1496 * DOC: Scanning and BSS list handling
1497 *
1498 * The scanning process itself is fairly simple, but cfg80211 offers quite
1499 * a bit of helper functionality. To start a scan, the scan operation will
1500 * be invoked with a scan definition. This scan definition contains the
1501 * channels to scan, and the SSIDs to send probe requests for (including the
1502 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1503 * probe. Additionally, a scan request may contain extra information elements
1504 * that should be added to the probe request. The IEs are guaranteed to be
1505 * well-formed, and will not exceed the maximum length the driver advertised
1506 * in the wiphy structure.
1507 *
1508 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1509 * it is responsible for maintaining the BSS list; the driver should not
1510 * maintain a list itself. For this notification, various functions exist.
1511 *
1512 * Since drivers do not maintain a BSS list, there are also a number of
1513 * functions to search for a BSS and obtain information about it from the
1514 * BSS structure cfg80211 maintains. The BSS list is also made available
1515 * to userspace.

2801 * @start_p2p_device: Start the given P2P device.

77765eaf
VT
2803 *
2804 * @set_mac_acl: Sets MAC address control list in AP and P2P GO mode.
2805 * Parameters include ACL policy, an array of MAC address of stations
2806 * and the number of MAC addresses. If there is already a list in driver
2807 * this new list replaces the existing one. Driver has to clear its ACL
2808 * when number of MAC addresses entries is passed as 0. Drivers which
2809 * advertise the support for MAC based ACL have to implement this callback.
04f39047

2810 *
2811 * @start_radar_detection: Start radar detection in the driver.
8bf24293
JM
2812 *
2813 * @update_ft_ies: Provide updated Fast BSS Transition information to the
2814 * driver. If the SME is in the driver/firmware, this information can be
2815 * used in building Authentication and Reassociation Request frames.
5de17984
AS
2816 *
2817 * @crit_proto_start: Indicates a critical protocol needs more link reliability
2818 * for a given duration (milliseconds). The protocol is provided so the
2819 * driver can take the most appropriate actions.
2820 * @crit_proto_stop: Indicates critical protocol no longer needs increased link
2821 * reliability. This operation can not fail.
be29b99a 2822 * @set_coalesce: Set coalesce parameters.
16ef1fe2 2823 *
97dc94f1
MK
2824 * @channel_switch: initiate channel-switch procedure (with CSA). Driver is
2825 * responsible for veryfing if the switch is possible. Since this is
2826 * inherently tricky driver may decide to disconnect an interface later
2827 * with cfg80211_stop_iface(). This doesn't mean driver can accept
2828 * everything. It should do it's best to verify requests and reject them
2829 * as soon as possible.

e16821bc

2833 * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the
2834 * given interface This is used e.g. for dynamic HT 20/40 MHz channel width
2835 * changes during the lifetime of the BSS.
960d01ac
JB
2836 *
2837 * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device
2838 * with the given parameters; action frame exchange has been handled by
2839 * userspace so this just has to modify the TX path to take the TS into
2840 * account.
2841 * If the admitted time is 0 just validate the parameters to make sure
2842 * the session can be created at all; it is valid to just always return
2843 * success for that but that may result in inefficient behaviour (handshake
2844 * with the peer followed by immediate teardown when the addition is later
2845 * rejected)
2846 * @del_tx_ts: remove an existing TX TS
6e0bd6c3
RL
2847 *
2848 * @join_ocb: join the OCB network with the specified parameters
2849 * (invoked with the wireless_dev mutex held)

2851 * (invoked with the wireless_dev mutex held)
1057d35e
AN
2852 *
2853 * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver
2854 * is responsible for continually initiating channel-switching operations
2855 * and returning to the base channel for communication with the AP.
2856 * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both
2857 * peers must be on the base channel when the call completes.

2858 * @start_nan: Start the NAN interface.
2859 * @stop_nan: Stop the NAN interface.
a442b761
AB
2860 * @add_nan_func: Add a NAN function. Returns negative value on failure.
2861 * On success @nan_func ownership is transferred to the driver and
2862 * it may access it outside of the scope of this function. The driver
2863 * should free the @nan_func when no longer needed by calling
2864 * cfg80211_free_nan_func().
2865 * On success the driver should assign an instance_id in the
2866 * provided @nan_func.
2867 * @del_nan_func: Delete a NAN function.
a5a9dcf2
AB
2868 * @nan_change_conf: changes NAN configuration. The changed parameters must
2869 * be specified in @changes (using &enum cfg80211_nan_conf_changes);
2870 * All other parameters must be ignored.
ce0ce13a
