Message-Id: <1494241863-32549-1-git-send-email-liuhangbin@gmail.com> Date: Mon, 8 May 2017 19:11:03 +0800 From: Hangbin Liu <liuhangbin@...il.com> To: netdev@...r.kernel.org Cc: Hangbin Liu <liuhangbin@...il.com> Subject: [PATCH net] ip6_tunnel: remove unreachable ICMP_REDIRECT code After call ip6_tnl_err(), the rel_type will be ether ICMPV6_DEST_UNREACH or ICMPV6_PKT_TOOBIG. We will never reach ICMP_REDIRECT. So remove it.
