>Description:
If I enable 6to4 with stf_interface_ipv4addr there is no way to set configuration for created interface using create_args_stf0 even though startup scripts create such configuration.
>How-To-Repeat:
cat << EOT >> /etc/rc.conf
ipv6_enable="YES"
stf_interface_ipv4addr="YOUR IP"
create_args_stf0="group ext"
EOT
ifconfig stf0 destroy
/etc/rc.d/network_ipv6 restart
ifconfig -g ext
# no interfaces listed
