p
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.

The
.Nm ieee80211
series of functions first appeared in
.Nx 1.5 ,
and were later ported to
.Fx 4.6
and
.Ox 3.6 .
