netfilter: nfnetlink_hook: missing chain family
The family is relevant for pseudo-families like NFPROTO_INET otherwise the user needs to rely on the hook function name to differentiate it from NFPROTO_IPV4 and NFPROTO_IPV6 names. Add nfnl_hook_chain_desc_attributes instead of using the existing NFTA_CHAIN_* attributes, since these do not provide a family number. Fixes: e2cf17d3774c ("netfilter: add new hook nfnl subsystem") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
