I don't think this is a good idea currently. Capability checking is
done after module autoloading, so any user can load ctnetlink,
ip_conntrack and all related modules. Please make sure to move
capability checking in nfnetlink before module loading first.

BTW: The same applies to ip_tables and ipt_ULOG through netlink
autoloading.
