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.

1334 * DOC: Scanning and BSS list handling
1335 *
1336 * The scanning process itself is fairly simple, but cfg80211 offers quite
1337 * a bit of helper functionality. To start a scan, the scan operation will
1338 * be invoked with a scan definition. This scan definition contains the
1339 * channels to scan, and the SSIDs to send probe requests for (including the
1340 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1341 * probe. Additionally, a scan request may contain extra information elements
1342 * that should be added to the probe request. The IEs are guaranteed to be
1343 * well-formed, and will not exceed the maximum length the driver advertised
1344 * in the wiphy structure.
1345 *
1346 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1347 * it is responsible for maintaining the BSS list; the driver should not
1348 * maintain a list itself. For this notification, various functions exist.
1349 *
1350 * Since drivers do not maintain a BSS list, there are also a number of
1351 * functions to search for a BSS and obtain information about it from the
1352 * BSS structure cfg80211 maintains. The BSS list is also made available
1353 * to userspace.

Johannes Berg5be83de2009-11-19 00:56:28 +01002549 * @WIPHY_FLAG_NETNS_OK: if not set, do not allow changing the netns of this
2550 * wiphy at all
2551 * @WIPHY_FLAG_PS_ON_BY_DEFAULT: if set to true, powersave will be enabled
2552 * by default -- this flag will be set depending on the kernel's default
2553 * on wiphy_new(), but can be changed by the driver if it has a good
2554 * reason to override the default
Johannes Berg9bc383d2009-11-19 11:55:19 +01002555 * @WIPHY_FLAG_4ADDR_AP: supports 4addr mode even on AP (with a single station
2556 * on a VLAN interface)
2557 * @WIPHY_FLAG_4ADDR_STATION: supports 4addr mode even as a station
Johannes Bergc0692b82010-08-27 14:26:53 +03002558 * @WIPHY_FLAG_CONTROL_PORT_PROTOCOL: This device supports setting the
2559 * control port protocol ethertype. The device also honours the
2560 * control_port_no_encrypt flag.
Johannes Berge31b8212010-10-05 19:39:30 +02002561 * @WIPHY_FLAG_IBSS_RSN: The device supports IBSS RSN.
Javier Cardona15d5dda2011-04-07 15:08:28 -07002562 * @WIPHY_FLAG_MESH_AUTH: The device supports mesh authentication by routing
2563 * auth frames to userspace. See @NL80211_MESH_SETUP_USERSPACE_AUTH.
Randy Dunlap1ba01452011-05-22 17:16:20 -07002564 * @WIPHY_FLAG_SUPPORTS_SCHED_SCAN: The device supports scheduled scans.
Vivek Natarajanf4b34b52011-08-29 14:23:03 +05302565 * @WIPHY_FLAG_SUPPORTS_FW_ROAM: The device supports roaming feature in the
2566 * firmware.
Eliad Pellercedb5412011-08-31 11:29:43 +03002567 * @WIPHY_FLAG_AP_UAPSD: The device supports uapsd on AP.
Arik Nemtsov109086c2011-09-28 14:12:50 +03002568 * @WIPHY_FLAG_SUPPORTS_TDLS: The device supports TDLS (802.11z) operation.
2569 * @WIPHY_FLAG_TDLS_EXTERNAL_SETUP: The device does not handle TDLS (802.11z)
2570 * link setup/discovery operations internally. Setup, discovery and
2571 * teardown packets should be sent through the @NL80211_CMD_TDLS_MGMT
2572 * command. When this flag is not set, @NL80211_CMD_TDLS_OPER should be
2573 * used for asking the driver/firmware to perform a TDLS operation.
Johannes Berg562a7482011-11-07 12:39:33 +01002574 * @WIPHY_FLAG_HAVE_AP_SME: device integrates AP SME
Johannes Berg5e7602302011-11-04 11:18:17 +01002575 * @WIPHY_FLAG_REPORTS_OBSS: the device will report beacons from other BSSes
2576 * when there are virtual interfaces in AP mode by calling
2577 * cfg80211_report_obss_beacon().
Arik Nemtsov87bbbe22011-11-10 11:28:55 +02002578 * @WIPHY_FLAG_AP_PROBE_RESP_OFFLOAD: When operating as an AP, the device
2579 * responds to probe-requests in hardware.
Johannes Berg7c4ef712011-11-18 15:33:48 +01002580 * @WIPHY_FLAG_OFFCHAN_TX: Device supports direct off-channel TX.
2581 * @WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL: Device supports remain-on-channel call.
Simon Wunderlich2f301ab2013-05-16 13:00:28 +02002582 * @WIPHY_FLAG_SUPPORTS_5_10_MHZ: Device supports 5 MHz and 10 MHz channels.
Simon Wunderlich16ef1fe2013-07-11 16:09:05 +02002583 * @WIPHY_FLAG_HAS_CHANNEL_SWITCH: Device supports channel switch in

4106 *
4107 * Test mode is a set of utility functions to allow drivers to
4108 * interact with driver-specific tools to aid, for instance,
4109 * factory programming.
4110 *
4111 * This chapter describes how drivers interact with it, for more
4112 * information see the nl80211 book's chapter on it.
