>Description:
This section are irrelevant: 

                 If a wlans_<interface> variable is set, an wlan(4) interface
                 will be created for each item in the list with the wlandev
                 argument set to interface.  Further wlan cloning arguments
                 may be passed to the ifconfig(8) create command by setting
                 the create_args_<interface> variable.  One or more wlan(4)
                 devices must be created for each wireless devices as of
                 FreeBSD 8.0.  Debugging flags for wlan(4) devices as set by
                 wlandebug(8) may be specified with an wlandebug_<interface>
                 variable.  The contents of this variable will be passed
                 directly to wlandebug(8).

and when setting up interface based the above, the interface does not start.

And this example are wrong too:

                 wlans_ath0="wlan0"
                 ifconfig_wlan0="DHCP WPA mode 11b"
