	Is there any way to make the userland programs work on top of
	IPv4-only kernel and IPv4/v6 kernel?  Like "have IPv4/IPv6 support,
	will raise error if user specifies filter that is not supported by
	the kernel"?

	NetBSD will ship compiled userland binaries.  It is pity to ask
	everyone to switch userland binaries when she switch the kernel.
