The wireless subsystem changed a lot since 10-STABLE, and there are no
more iwn interfaces shown via ifconfig.

You could query them as Adrian mentioned.

If you successfully upgraded your base system _too_ and not just the
kernel, then you should put a similar lines into rc.conf:

wlans_iwn0="wlan0"
ifconfig_wlan0="WPA DHCP country HU -wme -powersave"

And you should put the relevant firmware module's loading request into
/boot/loader.conf, this was mentioned in one mail before.
