i was able to get the interfaces to show up

iwn0: flags=8803<UP,BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 2290
        ether 9c:4e:36:9b:f2:90
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: IEEE 802.11 Wireless Ethernet autoselect mode 11b
        status: associated

then that :   ifconfig wlan0 create wlandev iwn0

wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 9c:4e:36:9b:f2:90

        bgscan bgscanintvl 300 bgscanidle 250 roam:rssi 7 roam:rate 1 wme

So its getting there, but i'm unable to scan

root at thinkbsd:/root # ifconfig wlan0 scan
root at thinkbsd:/root # ifconfig wlan0 list scan
root at thinkbsd:/root # ifconfig iwn0 scan
ifconfig: unable to get scan results
root at thinkbsd:/root # ifconfig iwn0 list scan
ifconfig: unable to get scan results

rc.conf has
ifconfig_wlan0="WPA DHCP"
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA DHCP"
wpa_supplicant_enable="YES"
wlandebug_wlan0="scan+auth+assoc"

and in loader.conf i have
if_iwlfw_load="YES"
if_iwi_load="YES"
legal.intel_iwi.license_ack=1



am i doing something wrong? or is it not fully supported yet?
