Bruce M Simpson 3f3f4cdba2 Initial import of documentation for net80211 interface code.
Of particular interest here is the ieee80211_radiotap(9) man page.

TODO: Flesh out ieee80211_node.9, ieee80211_proto.9.

.Sh DESCRIPTION
The
.Nm
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
.Vt SIOCS80211
and
.Vt SIOCG80211
ifioctls commands for 802.11 drivers.
The call signature is identical to that of the
.Vt if_ioctl
member found in
.Vt struct ifnet ,
however, many drivers store attributes such as
.Vt 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.
