Change 162137 by zec@zec_tpx32 on 2009/05/15 23:26:43

	When detaching and ifnet, clear ifp->if_afdata_initialized
	after completing iteration over all protocol families for
	possible dom_ifdetach.
	
	ifp->if_afdata_initialized needs to be clear for if_attach()
	to work properly on ifnets moved from one vnet to another.
