Subject: [nftables PATCH 1/2] rule: display hook info
Date: Sun,  9 Jun 2013 01:08:46 +0200	[thread overview]
Message-ID: <1370732927-23322-2-git-send-email-eric@regit.org> (raw)
In-Reply-To: <1370732927-23322-1-git-send-email-eric@regit.org>

It was not possible to restore a ruleset because of missing
hook information. This patch adds hooknum output to list
operation.
