>Description:
	/etc/rc.d/netif script doesn't destroy cloned interfaces,
	e.g. vlanXX, when called with restart parameter. This leads to
	impossibility to reconfigure cloned devices, because of 
	error produced by ifconfig. Before restart interfaces 
	one should destroy all cloned interfaces manually
>How-To-Repeat:
	add cloned_interfaces to /etc/rc.conf:
	cloned_interfaces="vlan2"
	add ifconfig_vlan2 to /etc/rc.conf:
	ifconfig_vlan2="vlan 2 vlandev ifXX 192.168.0.1 255.255.255.0"
	try to restart netifs two times
	look to:
	ifconfig: SIOCIFCREATE: File exists 
	error string, and look to vlan2 interface.
>Fix:

	n/a
