	I was curious because one of my colleague is trying to implement
	IPv6/IPsec testing tool on top of it and would like to backport
	it into KAME/*BSD (non-NetBSD), and he wondered if the interface
	would stay there for certain period of time or not.  It looks okay
	to use the interface for his purpose and he told me that he would
	give it a try.  Thanks.
