Subject: [PATCH 31/52] netfilter: nf_tables: remove hooks from family definition
Date: Mon, 8 Jan 2018 21:19:39 +0100 [thread overview]
Message-ID: <20180108202000.12989-32-pablo@netfilter.org> (raw)
In-Reply-To: <20180108202000.12989-1-pablo@netfilter.org>
They don't belong to the family definition, move them to the filter
chain type definition instead.
