Subject: [PATCH v2 2/6] ipv6: just match on ICMPV6_PKT_TOOBIG in those err_handle
Date: Fri, 13 Sep 2013 10:59:43 +0800	[thread overview]
Message-ID: <52327F9F.6080003@cn.fujitsu.com> (raw)
In-Reply-To: <52327F00.4040802@cn.fujitsu.com>

From: Duan Jiong <duanj.fnst@cn.fujitsu.com>

we don't handle NDISC_REDIRECTs here any more, and the match
on ICMPV6_DEST_UNREACH is meaningless.
