Message-Id: <1479075933-4491-7-git-send-email-pablo@netfilter.org>
Date: Sun, 13 Nov 2016 23:25:00 +0100
From: Pablo Neira Ayuso <pablo@...filter.org>
To: netfilter-devel@...r.kernel.org
Cc: davem@...emloft.net, netdev@...r.kernel.org
Subject: [PATCH 06/39] netfilter: nf_tables: use hook state from xt_action_param structure
Don't copy relevant fields from hook state structure, instead use the
one that is already available in struct xt_action_param.
This patch also adds a set of new wrapper functions to fetch relevant
hook state structure fields.
Signed-off-by: Pablo Neira Ayuso <pablo@...filter.org>
