netfilter: ipset: Introduce new operation to get both setname and family
ip[6]tables set match and SET target need to know the family of the set in order to reject adding rules which refer to a set with a non-mathcing family. Currently such rules are silently accepted and then ignored instead of generating a clear error message to the user, which is not helpful. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
