From: Herbert Xu Date: Thu, 6 Apr 2006 05:31:19 +0000 (-0700) Subject: [INET]: Use port unreachable instead of proto for tunnels X-Git-Tag: v2.6.17-rc2~291^2~26 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=45af08be6d120690d379cb8421ebaf9d9f86ba52;p=linux-2.6 [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.
