rc.conf behaviour has changed in regard of creating lagg interaces.

10.x needs this (copied from the handbook [1]):

ifconfig_bge0="up"
ifconfig_iwn0="ether 00:21:70:da:ae:37"
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto failover laggport bge0 laggport wlan0 DHCP"


11.x needs this:

ifconfig_bge0="up"
wlans_iwn0="wlan0"
create_args_wlan0="ether 00:21:70:da:ae:37" # new
ifconfig_wlan0="WPA"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto failover laggport bge0 laggport wlan0 DHCP"
