To run commands before a interface started, you need to create a
/etc/start_if.fec0,

           #!/bin/sh

           /usr/sbin/ngctl -f- <<-SEQ
                   mkpeer fec dummy fec
                   msg fec0: add_iface "bge0"
                   msg fec0: add_iface "bge1"
                   msg fec0: set_mode_inet
         SEQ

Then add fec0 to the network_interfaces variable in your /etc/rc.conf.
