wiphy device needs to be suspended. The variable wow
will
be NULL
or contain the enabled Wake-on-Wireless triggers that are
configured for the device.
wiphy device needs to be resumed
create a new virtual interface with the given name, must set the struct wireless_dev's iftype. Beware: You must create the new netdev in the wiphy's network namespace! Returns the netdev, or an ERR_PTR.
remove the virtual interface determined by ifindex.
change type/configuration of virtual interface, keep the struct wireless_dev's iftype updated.
add a key with the given parameters. mac_addr
will be NULL
when adding a group key.
get information about the key with the given parameters.
mac_addr
will be NULL
when requesting information for a group
key. All pointers given to the callback
function need not be valid
after it returns. This function should return an error if it is
not possible to retrieve the key, -ENOENT if it doesn't exist.
remove a key given the mac_addr
(NULL
for a group key)
and key_index
, return -ENOENT if the key doesn't exist.
set the default key on an interface
set the default management frame key on an interface
Add a beacon with given parameters, head
, interval
and dtim_period
will be valid, tail
is optional.
Change the beacon parameters for an access point mode interface. This should reject the call when no beacon has been configured.
Remove beacon configuration and stop sending the beacon.
Add a new station.
Remove a station; mac
may be NULL to remove all stations.
Modify a given station.
get station information for the station identified by mac
dump station callback -- resume dump at index idx
add a fixed mesh path
delete a given mesh path
change a given mesh path
get a mesh path for the given parameters
dump mesh path callback -- resume dump at index idx
Get the current mesh configuration
Update mesh parameters on a running mesh. The mask is a bitfield which tells us which parameters to set, and which to leave alone.
join the mesh network with the specified parameters
leave the current mesh network
Modify parameters for a given BSS.
Set TX queue parameters
Set channel for a given wireless interface. Some devices
may support multi-channel operation (by channel hopping) so cfg80211
doesn't verify much. Note, however, that the passed netdev may be
NULL
as well if the user requested changing the channel for the
device itself, or for a monitor interface.
Request to do a scan. If returning zero, the scan request is given
the driver, and will be valid until passed to cfg80211_scan_done
.
For scan results, call cfg80211_inform_bss
; you can call this outside
the scan/scan_done bracket too.
Request to authenticate with the specified peer
Request to (re)associate with the specified peer
Request to deauthenticate from the specified peer
Request to disassociate from the specified peer
Connect to the ESS with the specified parameters. When connected,
call cfg80211_connect_result
with status code WLAN_STATUS_SUCCESS
.
If the connection fails for some reason, call cfg80211_connect_result
with the status from the AP.
Disconnect from the BSS/ESS.
Join the specified IBSS (or create if necessary). Once done, call
cfg80211_ibss_joined
, also call that function when changing BSSID due
to a merge.
Leave the IBSS.
Notify that wiphy parameters have changed;
changed
bitfield (see enum wiphy_params_flags) describes which values
have changed. The actual parameter values are available in
struct wiphy. If returning an error, no value should be changed.
set the transmit power according to the parameters
store the current TX power into the dbm variable; return 0 if successful
set the WDS peer for a WDS interface
polls the hw rfkill line, use cfg80211 reporting functions to adjust rfkill hw state
run a test mode command
set the bitrate mask configuration
get site survey information.
Cache a PMKID for a BSSID. This is mostly useful for fullmac devices running firmwares capable of generating the (re) association RSN IE. It allows for faster roaming between WPA2 BSSIDs.
Delete a cached PMKID.
Flush all cached PMKIDs.
Request the driver to remain awake on the specified
channel for the specified duration to complete an off-channel
operation (e.g., public action frame exchange). When the driver is
ready on the requested channel, it must indicate this with an event
notification by calling cfg80211_ready_on_channel
.
Cancel an on-going remain-on-channel operation. This allows the operation to be terminated prior to timeout based on the duration value.
Transmit a management frame.
Cancel the wait time from transmitting a management frame on another channel
Configure WLAN power management. A timeout value of -1 allows the driver to adjust the dynamic ps timeout value.
Configure connection quality monitor RSSI threshold.
Notify driver that a management frame type was registered. Note that this callback may not sleep, and cannot run concurrently with itself.
Set antenna configuration (tx_ant, rx_ant) on the device.
Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
reject TX/RX mask combinations they cannot support by returning -EINVAL
(also see nl80211.h NL80211_ATTR_WIPHY_ANTENNA_TX
).
Get current antenna configuration from device (tx_ant, rx_ant).
Set tx and rx ring sizes.
Get tx and rx ring current and maximum sizes.
Tell the driver to start a scheduled scan.
Tell the driver to stop an ongoing scheduled scan. The driver_initiated flag specifies whether the driver itself has informed that the scan has stopped.
This struct is registered by fullmac card drivers and/or wireless stacks in order to handle configuration requests on their interfaces.
All callbacks except where otherwise noted should return 0 on success or a negative error code.
All operations are currently invoked under rtnl for consistency with the wireless extensions but this is subject to reevaluation as soon as this code is used more widely and we have a first user without wext.
