Subject: [PATCH 4/4] xfrm: Restrict extended sequence numbers to esp
Date: Tue, 29 Mar 2011 07:48:09 +0200	[thread overview]
Message-ID: <20110329054809.GL1290@secunet.com> (raw)
In-Reply-To: <20110329054552.GI1290@secunet.com>

The IPsec extended sequence numbers are fully implemented just for
esp. So restrict the usage to esp until other protocols have
support too.
