WLAN(4)		       FreeBSD Kernel Interfaces Manual		       WLAN(4)

NAME
     wlan -- generic 802.11 link-layer support

SYNOPSIS
     device wlan

DESCRIPTION
     The wlan device provides generic code to support 802.11 drivers, includ-
     ing host AP mode.	Currently it is	required for the wi(4),	an(4) and
     ath(4) drivers but	will eventually	be required by all 802.11 drivers.

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

	   ifconfig wi0	debug

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

	   sysctl debug.ieee80211=1

     causes additional messages	to be generated.  Many drivers will also dis-
     play the contents of each 802.11 frame sent and received when the inter-
     face is marked with both debugging	and link2; e.g.,

	   ifconfig wi0	debug link2

     Beware however that some management frames	may be processed entirely
     within the	device and not be received by the host.

COMPATIBILITY
     The module	name of	wlan was used to be compatible with NetBSD.
