.Sh DESCRIPTION
|
|
These
|
|
functions are typically invoked by drivers in response to requests
|
|
for information or to change settings from the userland.
|
|
.Pp
|
|
.\"
|
|
The
|
|
.Fn ieee80211_cfgget
|
|
and
|
|
.Fn ieee80211_cfgset
|
|
functions implement a legacy interface for getting and setting 802.11
|
|
interface attributes respectively.
|
|
The interface is compatible with the RIDs implemented by the legacy
|
|
.Xr owi 4
|
|
driver and used by the
|
|
.Xr wicontrol 8
|
|
utility.
|
|
.Pp
|
|
.\"
|
|
The
|
|
.Fn ieee80211_ioctl
|
|
function provides a default implementation of the
|
|
.Dv SIOCS80211
|
|
and
|
|
.Dv SIOCG80211
|
|
ifioctls commands for 802.11 drivers.
|
|
The call signature is identical to that of the
|
|
.Va if_ioctl
|
|
member found in
|
|
.Vt struct ifnet ,
|
|
however, many drivers store attributes such as
|
|
.Dv IEEE80211_IOC_STATIONNAME
|
|
in the driver's private soft state structure, so driver writers may prefer
|
|
to use this as the catch-all in a switch statement to avoid code duplication.
