Description Marat N.Afanasyev 2007-03-06 11:30:03 UTC
	/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:
	add ifconfig_vlan2 to /etc/rc.conf:
	ifconfig_vlan2="vlan 2 vlandev ifXX"
	try to restart netifs two times
	look to:
	ifconfig: SIOCIFCREATE: File exists 
	error string, and look to vlan2 interface.
Comment 1 Brooks Davis freebsd_committer 2007-03-07 20:42:06 UTC
The most realistinc solution to this problem is probably do simply
disable the restart case.  I don't think it's going to be practical to
support restart.

Comment 2 Marat N.Afanasyev 2007-03-08 06:08:47 UTC
I think that if we create cloned interfaces at start, we should destroy 
them when shutting down.

From rc.d/netif, you can use clonedown and then cloneup to reset cloned

  Destroy cloned interfaces at netif stop, netif restart and shutdown.
  This is especially important during shutdown because a child interface
  of lagg with WOL enabled will not enable WOL at interface shutdown and
  thus no WOL to wake up the device (and machine).
