.Dd September 25, 2003 .Dt WLAN 4 .Os .Sh NAME .Nm wlan .Nd generic 802.11 link-layer support .Sh SYNOPSIS .Cd "device wlan" .Sh DESCRIPTION The .Nm device provides generic code to support 802.11 drivers, including host AP mode. Currently it is required for the .Xr wi 4 , .Xr an 4 and .Xr ath 4 drivers but will eventually be required by all 802.11 drivers.

p If the associated interface is marked for debugging with, for example,

p .Dl "ifconfig wi0 debug"

p then messages describing the operation of the 802.11 protocol will be sent to the console. With the interface marked for debugging, doing:

p .Dl "sysctl debug.ieee80211=1"

p causes additional messages to be generated. Many drivers will also display the contents of each 802.11 frame sent and received when the interface is marked with both debugging and .Cm link2 ; e.g.,

p .Dl "ifconfig wi0 debug link2"

p Beware however that some management frames may be processed entirely within the device and not be received by the host. .Sh COMPATIBILITY The module name of .Nm was used to be compatible with .Nx . .Sh SEE ALSO .Xr an 4 , .Xr ath 4 , .Xr awi 4 , .Xr netintro 4 , .Xr wi 4 .Sh STANDARDS More information can be found in the IEEE 802.11 Standard. .Sh HISTORY The .Nm driver first appeared in .Fx 5.0 . .Sh AUTHORS Atsushi Onoe is the original author of this software. The .Nx support was adapted to .Fx by .An -nosplit .An Sam Leffler . This manual page was written by .An Tom Rhodes Aq trhodes@FreeBSD.org .
