what should happen with set/getsockopt(IPV6_CHECKSUM) on ICMPv6 socket?

	2292bis-02 says as follows,
>   An attempt to set IPV6_CHECKSUM for an ICMPv6 socket will fail.
	therefore, setsockopt(IPV6_CHECKSUM) on ICMPv6 socket will fail, but
	with what error code? (EINVAL? EOPNOTSUPP?)

	what should happen for getsockopt(IPV6_ICMPV6) on ICMPv6 socket?
	- always return 2?
	- raise error (error code?)
