From 7e223de84b73c621b90755dc4d8c8128e673b529 Mon Sep 17 00:00:00 2001 From: Anders Franzen Date: Tue, 19 Oct 2010 03:50:47 +0000 Subject: [PATCH] ip6_tunnel dont update the mtu on the route. The ip6_tunnel device did not unset the flag, IFF_XMIT_DST_RELEASE. This will make the dev layer to release the dst before calling the tunnel. The tunnel will not update any mtu/pmtu info, since it does not have a dst on the skb. Acked-by: Eric Dumazet Signed-off-by: David S.
