From: Guenter Roeck Date: Wed, 25 Mar 2015 15:08:37 +0000 (-0700) Subject: net: dsa: Handle non-bridge master change X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b06b107a4c190299e9e3f8dbcccfc7fe9e10c8cb;p=linux-beck.git 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.
