Hmmm.

combined with
> CONFIG_SUNRPC=y

is a combination that isn't going to work at the moment....

Options?

 - Move __ipv6_addr_type to lib/ ??
        Might not work for modules.
 - Disallow that combination in the .config.
        .. a bit harsh.
 - Only include IPv6 support in SUNRPC is a module or IPV6 is built-in
        A bit of a kludge..

Chuck?  Any ideas?
