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.

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.

1300 * DOC: Scanning and BSS list handling
1301 *
1302 * The scanning process itself is fairly simple, but cfg80211 offers quite
1303 * a bit of helper functionality. To start a scan, the scan operation will
1304 * be invoked with a scan definition. This scan definition contains the
1305 * channels to scan, and the SSIDs to send probe requests for (including the
1306 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1307 * probe. Additionally, a scan request may contain extra information elements
1308 * that should be added to the probe request. The IEs are guaranteed to be
1309 * well-formed, and will not exceed the maximum length the driver advertised
1310 * in the wiphy structure.
1311 *
1312 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1313 * it is responsible for maintaining the BSS list; the driver should not
1314 * maintain a list itself. For this notification, various functions exist.
1315 *
1316 * Since drivers do not maintain a BSS list, there are also a number of
1317 * functions to search for a BSS and obtain information about it from the
1318 * BSS structure cfg80211 maintains. The BSS list is also made available
1319 * to userspace.

2148 * Parameters include ACL policy, an array of MAC address of stations
2149 * and the number of MAC addresses. If there is already a list in driver
2150 * this new list replaces the existing one. Driver has to clear its ACL
2151 * when number of MAC addresses entries is passed as 0. Drivers which
2152 * advertise the support for MAC based ACL have to implement this callback.

Johannes Berg5be83de2009-11-19 00:56:28 +01002425 * @WIPHY_FLAG_STRICT_REGULATORY: tells us the driver for this device will

2438 * that passive scan flags and beaconing flags may not be lifted by

2443 * @WIPHY_FLAG_PS_ON_BY_DEFAULT: if set to true, powersave will be enabled
2444 * by default -- this flag will be set depending on the kernel's default
2445 * on wiphy_new(), but can be changed by the driver if it has a good
2446 * reason to override the default
Johannes Berg9bc383d2009-11-19 11:55:19 +01002447 * @WIPHY_FLAG_4ADDR_AP: supports 4addr mode even on AP (with a single station

2449 * @WIPHY_FLAG_4ADDR_STATION: supports 4addr mode even as a station
Johannes Bergc0692b82010-08-27 14:26:53 +03002450 * @WIPHY_FLAG_CONTROL_PORT_PROTOCOL: This device supports setting the

2452 * control_port_no_encrypt flag.
Johannes Berge31b8212010-10-05 19:39:30 +02002453 * @WIPHY_FLAG_IBSS_RSN: The device supports IBSS RSN.

2455 * auth frames to userspace. See @NL80211_MESH_SETUP_USERSPACE_AUTH.
Randy Dunlap1ba01452011-05-22 17:16:20 -07002456 * @WIPHY_FLAG_SUPPORTS_SCHED_SCAN: The device supports scheduled scans.
Vivek Natarajanf4b34b52011-08-29 14:23:03 +05302457 * @WIPHY_FLAG_SUPPORTS_FW_ROAM: The device supports roaming feature in the
2458 * firmware.
Eliad Pellercedb5412011-08-31 11:29:43 +03002459 * @WIPHY_FLAG_AP_UAPSD: The device supports uapsd on AP.
Arik Nemtsov109086c2011-09-28 14:12:50 +03002460 * @WIPHY_FLAG_SUPPORTS_TDLS: The device supports TDLS (802.11z) operation.

2462 * link setup/discovery operations internally. Setup, discovery and
2463 * teardown packets should be sent through the @NL80211_CMD_TDLS_MGMT
2464 * command. When this flag is not set, @NL80211_CMD_TDLS_OPER should be
2465 * used for asking the driver/firmware to perform a TDLS operation.
Johannes Berg562a7482011-11-07 12:39:33 +01002466 * @WIPHY_FLAG_HAVE_AP_SME: device integrates AP SME
Johannes Berg5e7602302011-11-04 11:18:17 +01002467 * @WIPHY_FLAG_REPORTS_OBSS: the device will report beacons from other BSSes

2469 * cfg80211_report_obss_beacon().
Arik Nemtsov87bbbe22011-11-10 11:28:55 +02002470 * @WIPHY_FLAG_AP_PROBE_RESP_OFFLOAD: When operating as an AP, the device
2471 * responds to probe-requests in hardware.
Johannes Berg7c4ef712011-11-18 15:33:48 +01002472 * @WIPHY_FLAG_OFFCHAN_TX: Device supports direct off-channel TX.

Simon Wunderlich2f301ab2013-05-16 13:00:28 +02002474 * @WIPHY_FLAG_SUPPORTS_5_10_MHZ: Device supports 5 MHz and 10 MHz channels.

Luis R. Rodriguez2784fe92010-12-15 19:24:11 -08002659 * @reg_notifier: the driver's regulatory notification callback,
2660 * note that if your driver uses wiphy_apply_custom_regulatory()
2661 * the reg_notifier's request can be passed as NULL
Johannes Bergd3236552009-04-20 14:31:42 +02002662 * @regd: the driver's regulatory domain, if one was requested via
2663 * the regulatory_hint() API. This can be used by the driver
2664 * on the reg_notifier() if it chooses to ignore future
2665 * regulatory domain changes caused by other drivers.
2666 * @signal_type: signal type reported in &struct cfg80211_bss.
2667 * @cipher_suites: supported cipher suites
2668 * @n_cipher_suites: number of supported cipher suites
Jouni Malinenb9a5f8ca2009-04-20 18:39:05 +02002669 * @retry_short: Retry limit for short frames (dot11ShortRetryLimit)
2670 * @retry_long: Retry limit for long frames (dot11LongRetryLimit)
2671 * @frag_threshold: Fragmentation threshold (dot11FragmentationThreshold);
2672 * -1 = fragmentation disabled, only odd values >= 256 used
2673 * @rts_threshold: RTS threshold (dot11RTSThreshold); -1 = RTS/CTS disabled

2676 * @addr_mask: If the device supports multiple MAC addresses by masking,
2677 * set this to a mask with variable bits set to 1, e.g. if the last
2678 * four bits are variable then set it to 00:...:00:0f. The actual
2679 * variable bits shall be determined by the interfaces added, with
2680 * interfaces not matching the mask being rejected to be brought up.
2681 * @n_addresses: number of addresses in @addresses.
2682 * @addresses: If the device has more than one address, set this pointer
2683 * to a list of addresses (6 bytes each). The first one will be used
2684 * by default for perm_addr. In this case, the mask should be set to
2685 * all-zeroes. In this case it is assumed that the device can handle
2686 * the same number of arbitrary MAC addresses.
