Subject: [PATCH nf-next RFC 1/8] netfilter: nf_tables: remove nhooks field from struct nft_af_info
Date: Sun, 31 Dec 2017 00:13:41 +0100 [thread overview]
Message-ID: <20171230231348.5497-2-pablo@netfilter.org> (raw)
In-Reply-To: <20171230231348.5497-1-pablo@netfilter.org>
We already validate the hook through bitmask, so this check is
superfluous.
Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
