SYNOPSIS

#include <net80211/ieee80211_var.h>

#include <net80211/ieee80211_ioctl.h>
int
ieee80211_cfgget(struct  ifnet  *ifp,  u_long  cmd,  caddr_t
data);
int
ieee80211_cfgset(struct  ifnet  *ifp,  u_long  cmd,  caddr_t
data);
int
ieee80211_ioctl(struct   ifnet  *ifp,  u_long  cmd,  caddr_t
data);

DESCRIPTION

These functions are typically invoked by drivers in response

to requests
for information or to change settings from the userland.

The ieee80211_cfgget() and ieee80211_cfgset() functions im

plement a
legacy interface for getting and setting 802.11 interface

attributes
respectively. The interface is compatible with the RIDs im

plemented by
the legacy owi(4) driver and used by the wicontrol(8) utili

ty.

The ieee80211_ioctl() function provides a default implemen

tation of the
SIOCS80211 and SIOCG80211 ifioctls commands for 802.11

drivers. The call
signature is identical to that of the if_ioctl member found

in struct
ifnet, however, many drivers store attributes such as
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.

HISTORY

The ieee80211 series of functions first appeared in NetBSD

1.5, and were
later ported to FreeBSD 4.6.
