From 45af08be6d120690d379cb8421ebaf9d9f86ba52 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 5 Apr 2006 22:31:19 -0700 Subject: [INET]: Use port unreachable instead of proto for tunnels This patch changes GRE and SIT to generate port unreachable instead of protocol unreachable errors when we can't find a matching tunnel for a packet. This removes the ambiguity as to whether the error is caused by no tunnel being found or by the lack of support for the given tunnel type. Signed-off-by: Herbert Xu Signed-off-by: David S.
