	there seems to be some config mistake within ISI (who hosts 
	tp.netbsd.org), regarding to link MTU setting of tunnel interface.
	i heard that they have changed the config so it should be better now.
	(at least, it is much better for me)

	i myself have experienced it before - Juniper sets tunnel interface MTU
	to infinity, and KAME uses 1280.
