34.Nd standard interface to IEEE 802.11 devices
35.Sh SYNOPSIS
36.In sys/types.h
37.In sys/socket.h
38.In net/if.h
39.In net/ethernet.h
40.In net80211/ieee80211_ioctl.h
41.Sh DESCRIPTION
42This section describes the standard programming
43interface to configure and retrieve status information
44for IEEE 802.11 devices that depend on the
45.Xr wlan 4
46module for operation.
47The interface is via one
48of the following
49.Xr ioctl 2
50calls on a socket:
51.Bl -tag -width ".Dv SIOCG80211"
52.It Dv SIOCG80211
53Get configuration or status information.
54.It Dv SIOCS80211
55Set configuration information.
56.El
57.Pp
58These requests are made via a modified
59.Vt ifreq
60structure.
61This structure is defined as follows:
62.Bd -literal
63struct ieee80211req {
64	char		i_name[IFNAMSIZ];	/* if_name, e.g. "wi0" */
65	uint16_t	i_type;			/* req type */
66	int16_t		i_val;			/* Index or simple value */
67	int16_t		i_len;			/* Index or simple value */
68	void		*i_data;		/* Extra data */
69};
70.Ed
71.Pp
72Requests that are not supported by the underlying device return
73-1 and set the global variable errno to
74.Er EOPNOTSUPP .
75.Dv SIOCG80211
76requests that return data to an application place small values in
77.Va i_val
78or in a user-specified buffer pointed to by
79.Va i_data .
80When an indirect buffer is used
81.Va i_len
82specifies how large the indirect buffer is and on return it is set by the
83system to the actual amount of data returned.
84.Dv SIOCS80211
85requests use a similar scheme with data passed to the system taken either
86from
87.Va i_val
88or an indirect buffer pointed to by
89.Va i_data .
90.Pp
91For
92.Dv SIOCG80211
93the following values of
94.Va i_type
95are valid:
96.Bl -tag -width indent
97.It Dv IEEE80211_IOC_AMPDU
98Return whether or not AMPDU is enabled in
99.Va i_val .
100AMPDU is an aggregation scheme that is part of the 802.11n specification
101and is used only when operating on an HT channel.
102The value returned is one of:
1030 (AMPDU disabled),
1041 (AMPDU enabled for transmit),
1052 (AMPDU enabled for receive),
106and
1073 (AMPDU enabled for transmit and receive).
108The 802.11n specification says a compliant station must receive AMPDU but
109may not support transmitting AMPDU frames.
110Disabling AMPDU receive is mainly useful for testing and working around bugs.
111.It Dv IEEE80211_IOC_AMPDU_DENSITY
112Return the minimum density for bursting AMPDU frames in
113.Va i_val .
114The value returned is one of:
1150 (no time restriction),
1161 (1/4 usec),
1172 (1/2 usec),
1183 (1 usec),
1194 (2 usec),
1205 (4 usec),
1216 (8 usec),
122and
1237 (16 usec).
124.It Dv IEEE80211_IOC_AMPDU_LIMIT
125Return the limit on the size of AMPDU frames in
126.Va i_val .
127The value returned is one of:
1280 (8 kilobytes),
1291 (16 kilobytes),
1302 (32 kilobytes),
131and
1323 (64 kilobytes).
133.It Dv IEEE80211_IOC_AMSDU
134Return whether or not AMSDU is enabled in
135.Va i_val .
136AMSDU is an aggregation scheme that is part of the 802.11n specification
137and is used only when operating on an HT channel.
138The value returned is one of:
1390 (AMSDU disabled),
1401 (AMSDU enabled for transmit),
1412 (AMSDU enabled for receive),
142and
1433 (AMSDU enabled for transmit and receive).
144The 802.11n specification says a compliant station must receive AMSDU but
145may not support transmitting AMSDU frames.
146Disabling AMSDU receive is mainly useful for testing and working around bugs.
147.It Dv IEEE80211_IOC_AMSDU_LIMIT
148Return the limit on the size of AMSDU frames in
149.Va i_val .
150The value returned is one of:
1513839 (bytes)
152and
1537935 (bytes).
154Note these values are specified by 802.11n; arbitrary values are not allowed.
155.It Dv IEEE80211_IOC_APBRIDGE
156Return whether AP bridging is enabled in
157.Va i_val .
158Normally packets sent between stations associated
159to the same access point are delivered without going through system layers
160that do packet filtering; when AP bridging is disabled packets are
161passed up the system to be forwarded using some other mechanism.
162This value will be non-zero when AP bridging is enabled and otherwise zero.
163.It Dv IEEE80211_IOC_APPIE
164Return an application information element via
165.Va i_data .
166Application IE's are maintained for many 802.11 frames; the
167request must identify the frame to return an IE for in
168.Va i_val .
169For example, to retrieve the IE sent in each Beacon frame
170.Va i_val
171would be set to
172.Va IEEE80211_FC0_SUBTYPE_BEACON | IEEE80211_FC0_TYPE_MGT .
173If no information element is installed then
174.Er EINVAL
175is returned.
176If the data buffer for returning data is too small to hold the information
177element the value is truncated; this permits querying the presence of
178data by requesting zero bytes of data be returned.
179.It Dv IEEE80211_IOC_AUTHMODE
180Return the current authentication mode in
181.Va i_val .
182Valid values are
183.Dv IEEE80211_AUTH_NONE
184(no authentication),
185.Dv IEEE80211_AUTH_OPEN
186(open authentication),
187.Dv IEEE80211_AUTH_SHARED
188(shared key authentication),
189.Dv IEEE80211_AUTH_8021X
190(802.1x only authentication),
191and
192.Dv IEEE80211_AUTH_WPA
193(WPA/802.11i/802.1x authentication).
194.It Dv IEEE80211_IOC_BEACON_INTERVAL
195Return the time between Beacon frames (in TU) in
196.Va i_val .
197.It Dv IEEE80211_IOC_BGSCAN
198Return whether background scanning is enabled in
199.Va i_val .
200When this value is non-zero and operating in station mode
201the station will periodically leave
202the current channel and scan for neighboring stations.
203See also
204.Dv IEEE80211_IOC_BGSCAN_IDLE
205and
206.Dv IEEE80211_IOC_BGSCAN_INTERVAL .
207.It Dv IEEE80211_IOC_BGSCAN_IDLE
208Return in
209.Va i_val
210the minimum time (msecs) a station must be idle
211(i.e. not transmitting or receiving frames)
212before it will do a background scan.
213See also
214.Dv IEEE80211_IOC_BGSCAN_INTERVAL .
215.It Dv IEEE80211_IOC_BGSCAN_INTERVAL
216Return in
217.Va i_val
218the minimum time (seconds) between background scan operations.
219See also
220.Dv IEEE80211_IOC_BGSCAN_IDLE .
221.It Dv IEEE80211_IOC_BMISSTHRESHOLD
222Return in
223.Va i_val
224the number of consecutive missed Beacon frames before the system will
225attempt to roam to a different/better access point.
226.It Dv IEEE80211_IOC_BSSID
227Return the MAC address for the current BSS identifier via
228.Va i_data .
229When the interface is running, the bssid is either the value
230configured locally (e.g. for an IBSS network started by the local station)
231or the value adopted when joining an existing network.
232For WDS interfaces this value is the address of the remote station.
233When the interface is not running, the bssid returned is the desired
234bssid, if any, that has been configured.
235.It Dv IEEE80211_IOC_BURST
236Return whether or not packet bursting is enabled in
237.Va i_val .
238If this value is non-zero then the system will try to send packets closely
239spaced to improve throughput.
240.It Dv IEEE80211_IOC_CHANINFO
241Return the set of available channels via
242.Va i_data .
243Note this data should be used by user applications to map between
244channel specifications (frequency and attributes) and IEEE channel numbers
245as user applications may not have the necessary information to do
246this directly (e.g. for 900MHz radios, operation in the Public Safety Band).
247.It Dv IEEE80211_IOC_CHANLIST
248Return the current list of usable channels via
249.Va i_data .
250The channel list is returned as a bit vector with bit N set to 1 if
251IEEE channel number N is available for use.
252.It Dv IEEE80211_IOC_CHANNEL
253Return the IEEE channel number of the current channel in
254.Va i_val .
255Note this request is deprecated; use
256.Dv IEEE80211_IOC_CURCHAN
257instead.
258.It Dv IEEE80211_IOC_COUNTERMEASURES
259Return whether TKIP Countermeasures are enabled in
260.Va i_val .
261This value will be non-zero when Countermeasures are enabled and
262otherwise zero.
263.It Dv IEEE80211_IOC_CURCHAN
264Return information for the current channel via
265.Va i_data .
266This information includes the IEEE channel number, the frequency, and
267attributes that describe the operating constraints (e.g. Passive Scan,
268DFS, usage restrictions).
269.It Dv IEEE80211_IOC_DEVCAPS
270Return device capabilities in the data buffer pointed at by
271.Va i_data .
272The buffer must be large enough to return the number of available
273channels but otherwise may be made small to limit how much information
274is returned.
275.It Dv IEEE80211_IOC_DFS
276Return whether or not Dynamic Frequency Selection (DFS) is enabled in
277.Va i_val .
278DFS embodies several facilities including detection of overlapping
279radar signals, dynamic transmit power control, and channel selection
280according to a least-congested criteria.
281DFS support is mandatory for some 5GHz frequencies in certain
282locales (e.g. ETSI).
283By default DFS is enabled according to the regulatory definitions
284and the current country code, regdomain, and channel.
285.It Dv IEEE80211_IOC_DOTD
286Return whether or not 802.11d support is enabled in
287.Va i_val .
288When 802.11d is enabled in station mode, Beacon frames that advertise
289a country code different than the currently configured country code will
290cause an event to be dispatched to user applications.
291This event can be used by the station to adopt that country code and
292operate according to the associated regulatory constraints.
293When operating as an access point with 802.11d enabled the Beacon and
294ProbeResponse frames transmitted will advertise the current regulatory
295domain settings.
296.It Dv IEEE80211_IOC_DOTH
297Return whether 802.11h support is enabled in
298.Va i_val .
299When 802.11h is enabled Beacon and ProbeResponse frames will have
300the SpectrumMgt bit set in the capabilities field and
301country and power constraint information elements will be present.
302802.11h support also includes handling Channel Switch Announcements (CSA)
303which are a mechanism to coordinate channel changes by an access point.
304By default 802.11h is enabled if the device is capable.
305.It Dv IEEE80211_IOC_DROPUNENCRYPTED
306Return, in
307.Va i_val ,
308whether unencrypted packets transmit/received should be discarded.
309This value will be zero if unencrypted packets will be accepted and
310non-zero if they are to be discarded.
311.It Dv IEEE80211_IOC_DTIM_PERIOD
312Return the period (in beacon intervals) between DTIM events in
313.Va i_val .
314.It Dv IEEE80211_IOC_DWDS
315Return, in
316.Va i_val ,
317whether or not Dynamic WDS support is enabled.
318Dynamic WDS is a facility by which packets may be tunneled over normal
319Infrastructure BSS associations using 4-address (WDS) frames.
320.It Dv IEEE80211_IOC_FF
321Return, in
322.Va i_val ,
323whether Atheros fast-frames support is enabled.
324Fast-frames is a non-standard protocol extension that aggregates multiple
325frames to improve throughput.
326Note that enabling fast-frames support does not guarantee use;
327the client and access point must negotiate its use.
328.It Dv IEEE80211_IOC_FRAGTHRESHOLD
329Return, in
330.Va i_val ,
331the threshold (in bytes) for enabling fragmentation frames.
332Packets larger than this value will automatically be split into multiple
333fragmented frames that are sent one after the other.
334.It Dv IEEE80211_IOC_GREENFIELD
335Return, in
336.Va i_val ,
337whether or not Greenfield preamble use is enabled.
338This  setting is meaningful only when operating with 802.11n on an HT channel.
339.It Dv IEEE80211_IOC_HIDESSID
340Return, in
341.Va i_val ,
342whether SSID hiding/cloaking is enabled.
343SSID hiding is only meaningful when operating as an access point.
344When this is enabled Beacon frames do not include the SSID and
345ProbeRequest frames are not answered unless they include the AP's SSID.
346This value will be non-zero when SSID hiding is enabled and otherwise zero.
347.It Dv IEEE80211_IOC_HTCOMPAT
348Return, in
349.Va i_val ,
350whether or not 802.11n compatibility support is enabled.
351The 802.11n protocol specification went through several incompatible iterations.
352Some vendors implemented 11n support to older specifications that
353will not interoperate with a purely 11n-compliant station.
354In particular the information elements included in management frames
355for old devices are different.
356When compatibility support is enabled both standard and compatible data
357will be provided and/or accepted.
358.It Dv IEEE80211_IOC_HTCONF
359Return the setting for automatic promotion of HT channels in
360.Va i_val .
361Promotion happens when the system must select a channel and may choose
362between legacy, HT20, and HT40 operation (e.g. when scanning).
363Valid values are:
3640 (do not promote, use legacy),
3651 (promote to HT20),

379Return the maximum acceptable hop count in an HWMP path in
380.Va i_val .
381.It Dv IEEE80211_IOC_HWMP_ROOTMODE

390(send broadcast Path Request frames and force replies)
391and
392.Dv IEEE80211_HWMP_ROOTMODE_RANN
393(send broadcast Root Announcement (RANN) frames).

395Return the underlying hardware
396.Xr device 9
397name in the buffer pointed to by
398.Va i_data
399and the name length including terminating NUL character in
400.Va i_len .
401If the buffer length is too small to hold the full name
402.Er EINVAL
403will be returned.
404.It Dv IEEE80211_IOC_INACTIVITY
405Return whether or not the system handles inactivity processing in
406.Va i_val .
407When inactivity processing is enabled the system will track stations
408that have not transmitted frames and periodically probe them to
409check if they are still present.
410Stations that are inactive and do not respond to probes are dropped.
411.It Dv IEEE80211_IOC_MACCMD
412Return information about the state of the MAC address
413access control list (ACL) system.
414There are two requests supported:

467(power save operation is enabled).
468.It Dv IEEE80211_IOC_POWERSAVESLEEP
469Return the powersave sleep time in TU in
470.Va i_val .
471This value is also termed the listen interval and represents the maximum time
472a station will sleep before waking to retrieve packets buffered by
473an access point.
474.It Dv IEEE80211_IOC_PRIVACY
475Return the current MLME setting for PRIVACY in
476.Va i_val .
477When PRIVACY is enabled all data packets must be encrypted.
478This value will be zero if PRIVACY is disabled and
479non-zero when PRIVACY is enabled.
480.It Dv IEEE80211_IOC_PROTMODE
481Return the current 802.11g protection mode in
