Ruslan Ermilov 2e77778053 Fixed document title (should be in all uppercase).
List all functions in the NAME section so they appear in whatis(1).
Assorted fixes (mostly markup).

.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.
