	use either of the following.
	# ifconfig gif0 inet6 3ffe:xxx:x:x::39 3ffe:xxx:x:x::38 prefixlen 128 \
		alias
	OR
	# ifconfig gif0 inet6 3ffe:xxx:x:x::39 prefixlen 127 alias

	you are now using two address with /127:
	# ifconfig gif0 inet6 3ffe:xxx:x:x::39 3ffe:xxx:x:x::38 prefixlen 127 \
		alias
	which is rather ambiguous/redundant.
