From a46496ce38eeb401344d5623c1960dbf2f1769be Mon Sep 17 00:00:00 2001 From: Matt Bennett Date: Wed, 23 Sep 2015 16:58:31 +1200 Subject: [PATCH] ip6_gre: Reduce log level in ip6gre_err() to debug Currently error log messages in ip6gre_err are printed at 'warn' level. This is different to most other tunnel types which don't print any messages. These log messages don't provide any information that couldn't be deduced with networking tools. Also it can be annoying to have one end of the tunnel go down and have the logs fill with pointless messages such as "Path to destination invalid or inactive!". This patch reduces the log level of these messages to 'dbg' level to bring the visible behaviour into line with other tunnel types. Signed-off-by: Matt Bennett Signed-off-by: David S.
