	protosw has been used in various protocols so i would like to keep
	it as is (changing it will bring up compatibility issue with various
	experimental code available in the world).
	ip6protosw has a big reason to be different (kernel stack usage
	against long chain of headers).

	basically ip6protosw just needs to be in sync with protosw.
	I believe we can matinain them.
