Ref.:

g1-254(10.1-S)[7] egrep 'ifconfig|wlan|lagg' /etc/rc.conf | grep -v '^#'
ifconfig_em0="up"
ifconfig_iwn0="ether 34:e6:d7:3c:4a:93"
wlans_iwn0=wlan0
ifconfig_wlan0="WPA"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto failover laggport em0 laggport wlan0 DHCP"
g1-254(10.1-S)[8] ifconfig iwn0
iwn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290
        ether 34:e6:d7:3c:4a:93
