Subject: [PATCH 01/53] netfilter: ipvs: don't check for presence of nat extension
Date: Mon, 1 May 2017 12:46:28 +0200 [thread overview]
Message-ID: <1493635640-24325-2-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1493635640-24325-1-git-send-email-pablo@netfilter.org>
From: Florian Westphal <fw@strlen.de>
Check for the NAT status bits, they are set once conntrack needs NAT in source or
reply direction, this is slightly faster than nfct_nat() as that has to check the
extension area.
