Add IEEE80211_IOC_IC_NAME to query the ic_name field and in ifconfig to print the parent interface again. This functionality was lost around r287197. It helps in case of multiple wlan interfaces and multiple underlying hardware devices to keep track which wlan interface belongs to which physical device.

.Sh DESCRIPTION
|
|
This section describes the standard programming
|
|
interface to configure and retrieve status information
|
|
for IEEE 802.11 devices that depend on the
|
|
.Xr wlan 4
|
|
module for operation.
|
|
The interface is via one
|
|
of the following
|
|
.Xr ioctl 2
|
|
calls on a socket:
|
|
.Bl -tag -width ".Dv SIOCG80211"
|
|
.It Dv SIOCG80211
|
|
Get configuration or status information.
|
|
.It Dv SIOCS80211
|
|
Set configuration information.
|
|
.El
|
|
.Pp
|
|
These requests are made via a modified
|
|
.Vt ifreq
|
|
structure.
|
|
This structure is defined as follows:
|
|
.Bd -literal
|
|
struct ieee80211req {
|
|
char i_name[IFNAMSIZ]; /* if_name, e.g. "wi0" */
|
|
uint16_t i_type; /* req type */
|
|
int16_t i_val; /* Index or simple value */
|
|
int16_t i_len; /* Index or simple value */
|
|
void *i_data; /* Extra data */
|
|
};
|
|
.Ed
|
|
.Pp
|
|
Requests that are not supported by the underlying device return
|
|
-1 and set the global variable errno to
|
|
.Er EOPNOTSUPP .
|
|
.Dv SIOCG80211
|
|
requests that return data to an application place small values in
|
|
.Va i_val
|
|
or in a user-specified buffer pointed to by
|
|
.Va i_data .
|
|
When an indirect buffer is used
|
|
.Va i_len
|
|
specifies how large the indirect buffer is and on return it is set by the
|
|
system to the actual amount of data returned.
|
|
.Dv SIOCS80211
|
|
requests use a similar scheme with data passed to the system taken either
|
|
from
|
|
.Va i_val
|
|
or an indirect buffer pointed to by
|
|
.Va i_data .
|
|
.Pp
|
|
For
|
|
.Dv SIOCG80211
|
|
the following values of
|
|
.Va i_type
|
|
are valid:
|
|
.Bl -tag -width indent
|
|
.It Dv IEEE80211_IOC_AMPDU
|
|
Return whether or not AMPDU is enabled in
|
|
.Va i_val .
|
|
AMPDU is an aggregation scheme that is part of the 802.11n specification
|
|
and is used only when operating on an HT channel.
|
|
The value returned is one of:
|
|
0 (AMPDU disabled),
|
|
1 (AMPDU enabled for transmit),
|
|
2 (AMPDU enabled for receive),
|
|
and
|
|
3 (AMPDU enabled for transmit and receive).
|
|
The 802.11n specification says a compliant station must receive AMPDU but
|
|
may not support transmitting AMPDU frames.
|
|
Disabling AMPDU receive is mainly useful for testing and working around bugs.
|
|
.It Dv IEEE80211_IOC_AMPDU_DENSITY
|
|
Return the minimum density for bursting AMPDU frames in
|
|
.Va i_val .
|
|
The value returned is one of:
|
|
0 (no time restriction),
|
|
1 (1/4 usec),
|
|
2 (1/2 usec),
|
|
3 (1 usec),
|
|
4 (2 usec),
|
|
5 (4 usec),
|
|
6 (8 usec),
|
|
and
|
|
7 (16 usec).
|
|
.It Dv IEEE80211_IOC_AMPDU_LIMIT
|
|
Return the limit on the size of AMPDU frames in
|
|
.Va i_val .
|
|
The value returned is one of:
|
|
0 (8 kilobytes),
|
|
1 (16 kilobytes),
|
|
2 (32 kilobytes),
|
|
and
|
|
3 (64 kilobytes).
|
|
.It Dv IEEE80211_IOC_AMSDU
|
|
Return whether or not AMSDU is enabled in
|
|
.Va i_val .
|
|
AMSDU is an aggregation scheme that is part of the 802.11n specification
|
|
and is used only when operating on an HT channel.
|
|
The value returned is one of:
|
|
0 (AMSDU disabled),
|
|
1 (AMSDU enabled for transmit),
|
|
2 (AMSDU enabled for receive),
|
|
and
|
|
3 (AMSDU enabled for transmit and receive).
|
|
The 802.11n specification says a compliant station must receive AMSDU but
|
|
may not support transmitting AMSDU frames.
|
|
Disabling AMSDU receive is mainly useful for testing and working around bugs.
|
|
.It Dv IEEE80211_IOC_AMSDU_LIMIT
|
|
Return the limit on the size of AMSDU frames in
|
|
.Va i_val .
|
|
The value returned is one of:
|
|
3839 (bytes)
|
|
and
|
|
7935 (bytes).
|
|
Note these values are specified by 802.11n; arbitrary values are not allowed.
|
|
.It Dv IEEE80211_IOC_APBRIDGE
|
|
Return whether AP bridging is enabled in
|
|
.Va i_val .
|
|
Normally packets sent between stations associated
|
|
to the same access point are delivered without going through system layers
|
|
that do packet filtering; when AP bridging is disabled packets are
|
|
passed up the system to be forwarded using some other mechanism.
|
|
This value will be non-zero when AP bridging is enabled and otherwise zero.
|
|
.It Dv IEEE80211_IOC_APPIE
|
|
Return an application information element via
|
|
.Va i_data .
|
|
Application IE's are maintained for many 802.11 frames; the
|
|
request must identify the frame to return an IE for in
|
|
.Va i_val .
|
|
For example, to retrieve the IE sent in each Beacon frame
|
|
.Va i_val
|
|
would be set to
|
|
.Va IEEE80211_FC0_SUBTYPE_BEACON | IEEE80211_FC0_TYPE_MGT .
|
|
If no information element is installed then
|
|
.Er EINVAL
|
|
is returned.
|
|
If the data buffer for returning data is too small to hold the information
|
|
element the value is truncated; this permits querying the presence of
|
|
data by requesting zero bytes of data be returned.
|
|
.It Dv IEEE80211_IOC_AUTHMODE
|
|
Return the current authentication mode in
|
|
.Va i_val .
|
|
Valid values are
|
|
.Dv IEEE80211_AUTH_NONE
|
|
(no authentication),
|
|
.Dv IEEE80211_AUTH_OPEN
|
|
(open authentication),
|
|
.Dv IEEE80211_AUTH_SHARED
|
|
(shared key authentication),
|
|
.Dv IEEE80211_AUTH_8021X
|
|
(802.1x only authentication),
|
|
and
|
|
.Dv IEEE80211_AUTH_WPA
|
|
(WPA/802.11i/802.1x authentication).
|
|
.It Dv IEEE80211_IOC_BEACON_INTERVAL
|
|
Return the time between Beacon frames (in TU) in
|
|
.Va i_val .
|
|
.It Dv IEEE80211_IOC_BGSCAN
|
|
Return whether background scanning is enabled in
|
|
.Va i_val .
|
|
When this value is non-zero and operating in station mode
|
|
the station will periodically leave
|
|
the current channel and scan for neighboring stations.
|
|
See also
|
|
.Dv IEEE80211_IOC_BGSCAN_IDLE
|
|
and
|
|
.Dv IEEE80211_IOC_BGSCAN_INTERVAL .
|
|
.It Dv IEEE80211_IOC_BGSCAN_IDLE
|
|
Return in
|
|
.Va i_val
|
|
the minimum time (msecs) a station must be idle
|
|
(i.e. not transmitting or receiving frames)
|
|
before it will do a background scan.
|
|
See also
|
|
.Dv IEEE80211_IOC_BGSCAN_INTERVAL .
|
|
.It Dv IEEE80211_IOC_BGSCAN_INTERVAL
|
|
Return in
|
|
.Va i_val
|
|
the minimum time (seconds) between background scan operations.
|
|
See also
|
|
.Dv IEEE80211_IOC_BGSCAN_IDLE .
|
|
.It Dv IEEE80211_IOC_BMISSTHRESHOLD
|
|
Return in
|
|
.Va i_val
|
|
the number of consecutive missed Beacon frames before the system will
|
|
attempt to roam to a different/better access point.
|
|
.It Dv IEEE80211_IOC_BSSID
|
|
Return the MAC address for the current BSS identifier via
|
|
.Va i_data .
|
|
When the interface is running, the bssid is either the value
|
|
configured locally (e.g. for an IBSS network started by the local station)
|
|
or the value adopted when joining an existing network.
|
|
For WDS interfaces this value is the address of the remote station.
|
|
When the interface is not running, the bssid returned is the desired
|
|
bssid, if any, that has been configured.
|
|
.It Dv IEEE80211_IOC_BURST
|
|
Return whether or not packet bursting is enabled in
|
|
.Va i_val .
|
|
If this value is non-zero then the system will try to send packets closely
|
|
spaced to improve throughput.
|
|
.It Dv IEEE80211_IOC_CHANINFO
|
|
Return the set of available channels via
|
|
.Va i_data .
|
|
Note this data should be used by user applications to map between
|
|
channel specifications (frequency and attributes) and IEEE channel numbers
|
|
as user applications may not have the necessary information to do
|
|
this directly (e.g. for 900MHz radios, operation in the Public Safety Band).
|
|
.It Dv IEEE80211_IOC_CHANLIST
|
|
Return the current list of usable channels via
|
|
.Va i_data .
|
|
The channel list is returned as a bit vector with bit N set to 1 if
|
|
IEEE channel number N is available for use.
|
|
.It Dv IEEE80211_IOC_CHANNEL
|
|
Return the IEEE channel number of the current channel in
|
|
.Va i_val .
|
|
Note this request is deprecated; use
|
|
.Dv IEEE80211_IOC_CURCHAN
|
|
instead.
|
|
.It Dv IEEE80211_IOC_COUNTERMEASURES
|
|
Return whether TKIP Countermeasures are enabled in
|
|
.Va i_val .
|
|
This value will be non-zero when Countermeasures are enabled and
|
|
otherwise zero.
|
|
.It Dv IEEE80211_IOC_CURCHAN
|
|
Return information for the current channel via
|
|
.Va i_data .
|
|
This information includes the IEEE channel number, the frequency, and
|
|
attributes that describe the operating constraints (e.g. Passive Scan,
|
|
DFS, usage restrictions).
|
|
.It Dv IEEE80211_IOC_DEVCAPS
|
|
Return device capabilities in the data buffer pointed at by
|
|
.Va i_data .
|
|
The buffer must be large enough to return the number of available
|
|
channels but otherwise may be made small to limit how much information
|
|
is returned.
|
|
.It Dv IEEE80211_IOC_DFS
|
|
Return whether or not Dynamic Frequency Selection (DFS) is enabled in
|
|
.Va i_val .
|
|
DFS embodies several facilities including detection of overlapping
|
|
radar signals, dynamic transmit power control, and channel selection
|
|
according to a least-congested criteria.
|
|
DFS support is mandatory for some 5GHz frequencies in certain
|
|
locales (e.g. ETSI).
|
|
By default DFS is enabled according to the regulatory definitions
|
|
and the current country code, regdomain, and channel.
|
|
.It Dv IEEE80211_IOC_DOTD
|
|
Return whether or not 802.11d support is enabled in
|
|
.Va i_val .
|
|
When 802.11d is enabled in station mode, Beacon frames that advertise
|
|
a country code different than the currently configured country code will
|
|
cause an event to be dispatched to user applications.
|
|
This event can be used by the station to adopt that country code and
|
|
operate according to the associated regulatory constraints.
|
|
When operating as an access point with 802.11d enabled the Beacon and
|
|
ProbeResponse frames transmitted will advertise the current regulatory
|
|
domain settings.
|
|
.It Dv IEEE80211_IOC_DOTH
|
|
Return whether 802.11h support is enabled in
|
|
.Va i_val .
|
|
When 802.11h is enabled Beacon and ProbeResponse frames will have
|
|
the SpectrumMgt bit set in the capabilities field and
|
|
country and power constraint information elements will be present.
|
|
802.11h support also includes handling Channel Switch Announcements (CSA)
|
|
which are a mechanism to coordinate channel changes by an access point.
|
|
By default 802.11h is enabled if the device is capable.
|
|
.It Dv IEEE80211_IOC_DROPUNENCRYPTED
|
|
Return, in
|
|
.Va i_val ,
|
|
whether unencrypted packets transmit/received should be discarded.
|
|
This value will be zero if unencrypted packets will be accepted and
|
|
non-zero if they are to be discarded.
|
|
.It Dv IEEE80211_IOC_DTIM_PERIOD
|
|
Return the period (in beacon intervals) between DTIM events in
|
|
.Va i_val .
|
|
.It Dv IEEE80211_IOC_DWDS
|
|
Return, in
|
|
.Va i_val ,
|
|
whether or not Dynamic WDS support is enabled.
|
|
Dynamic WDS is a facility by which packets may be tunneled over normal
|
|
Infrastructure BSS associations using 4-address (WDS) frames.
|
|
.It Dv IEEE80211_IOC_FF
|
|
Return, in
|
|
.Va i_val ,
|
|
whether Atheros fast-frames support is enabled.
|
|
Fast-frames is a non-standard protocol extension that aggregates multiple
|
|
frames to improve throughput.
|
|
Note that enabling fast-frames support does not guarantee use;
|
|
the client and access point must negotiate its use.
|
|
.It Dv IEEE80211_IOC_FRAGTHRESHOLD
|
|
Return, in
|
|
.Va i_val ,
|
|
the threshold (in bytes) for enabling fragmentation frames.
|
|
Packets larger than this value will automatically be split into multiple
|
|
fragmented frames that are sent one after the other.
|
|
.It Dv IEEE80211_IOC_GREENFIELD
|
|
Return, in
|
|
.Va i_val ,
|
|
whether or not Greenfield preamble use is enabled.
|
|
This setting is meaningful only when operating with 802.11n on an HT channel.
|
|
.It Dv IEEE80211_IOC_HIDESSID
|
|
Return, in
|
|
.Va i_val ,
|
|
whether SSID hiding/cloaking is enabled.
|
|
SSID hiding is only meaningful when operating as an access point.
|
|
When this is enabled Beacon frames do not include the SSID and
|
|
ProbeRequest frames are not answered unless they include the AP's SSID.
|
|
This value will be non-zero when SSID hiding is enabled and otherwise zero.
|
|
.It Dv IEEE80211_IOC_HTCOMPAT
|
|
Return, in
|
|
.Va i_val ,
|
|
whether or not 802.11n compatibility support is enabled.
|
|
The 802.11n protocol specification went through several incompatible iterations.
|
|
Some vendors implemented 11n support to older specifications that
|
|
will not interoperate with a purely 11n-compliant station.
|
|
In particular the information elements included in management frames
|
|
for old devices are different.
|
|
When compatibility support is enabled both standard and compatible data
|
|
will be provided and/or accepted.
|
|
.It Dv IEEE80211_IOC_HTCONF
|
|
Return the setting for automatic promotion of HT channels in
|
|
.Va i_val .
|
|
Promotion happens when the system must select a channel and may choose
|
|
between legacy, HT20, and HT40 operation (e.g. when scanning).
|
|
Valid values are:
|
|
0 (do not promote, use legacy),
|
|
1 (promote to HT20),
|
|
and
|
|
2 (promote to HT40).
|
|
.It Dv IEEE80211_IOC_HTPROTMODE
|
|
Return, in
|
|
.Va i_val ,
|
|
the technique used to protect HT frames in a mixed 802.11n network.
|
|
Valid values are:
|
|
.Dv IEEE80211_PROTMODE_OFF
|
|
(no protection enabled)
|
|
and
|
|
.Dv IEEE80211_PROTMODE_RTSCTS
|
|
(send RTS and wait for CTS).
|
|
.It Dv IEEE80211_IOC_HWMP_MAXHOPS
|
|
Return the maximum acceptable hop count in an HWMP path in
|
|
.Va i_val .
|
|
.It Dv IEEE80211_IOC_HWMP_ROOTMODE
|
|
Return the setting for Mesh root mode operation in
|
|
.Va i_val .
|
|
Valid values are:
|
|
.Dv IEEE80211_HWMP_ROOTMODE_DISABLED
|
|
(root mode is disabled),
|
|
.Dv IEEE80211_HWMP_ROOTMODE_NORMAL
|
|
(send broadcast Path Request frames),
|
|
.Dv IEEE80211_HWMP_ROOTMODE_PROACTIVE
|
|
(send broadcast Path Request frames and force replies)
|
|
and
|
|
.Dv IEEE80211_HWMP_ROOTMODE_RANN
|
|
(send broadcast Root Announcement (RANN) frames).
|
|
.It Dv IEEE80211_IOC_IC_NAME
|
|
Return the underlying hardware
|
|
.Xr device 9
|
|
name in the buffer pointed to by
|
|
.Va i_data
|
|
and the name length including terminating NUL character in
|
|
.Va i_len .
|
|
If the buffer length is too small to hold the full name
|
|
.Er EINVAL
|
|
will be returned.
|
|
.It Dv IEEE80211_IOC_INACTIVITY
|
|
Return whether or not the system handles inactivity processing in
|
|
.Va i_val .
|
|
When inactivity processing is enabled the system will track stations
|
|
that have not transmitted frames and periodically probe them to
|
|
check if they are still present.
|
|
Stations that are inactive and do not respond to probes are dropped.
|
|
.It Dv IEEE80211_IOC_MACCMD
|
|
Return information about the state of the MAC address
|
|
access control list (ACL) system.
|
|
There are two requests supported:
|
|
.Dv IEEE80211_MACCMD_POLICY
|
|
(to retrieve the current policy in
|
|
.Va i_val ),
|
|
and
|
|
.Dv IEEE80211_MACCMD_LIST
|
|
to retrieve the list installed/active ACL's via
|
