From b06b107a4c190299e9e3f8dbcccfc7fe9e10c8cb Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 25 Mar 2015 08:08:37 -0700 Subject: [PATCH] net: dsa: Handle non-bridge master change Master change notifications may occur other than when joining or leaving a bridge, for example when being added to or removed from a bond or Open vSwitch. In that case, do nothing instead of asking the switch driver to remove a port from a bridge that it didn't join. Signed-off-by: Guenter Roeck Acked-by: Florian Fainelli Signed-off-by: David S.
