IEEE80211_IOCTL(9) MidnightBSD Kernel Developer’s Manual IEEE80211_IOCTL(9)

NAME

ieee80211_cfgget, ieee80211_cfgset, ieee80211_ioctl — 802.11 interface ioctl commands

SYNOPSIS

#include <net80211/ieee80211_var.h>
#include <net80211/ieee80211_proto.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 implement a legacy interface for getting and setting 802.11 interface attributes respectively.

The ieee80211_ioctl() function provides a default implementation 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.
