Date: Tue, 10 Mar 2015 15:09:42 +0800 From: Zhu Yanjun <Yanjun.Zhu@...driver.com> To: <netdev@...r.kernel.org>, <davem@...hat.com> Subject: [PATCH 1/1] bridge: turn off carrier when the bridge is created When a bridge interface is created, there is no any sub interface in it. In this case, the packets should not go to this bridge interface. As such, carrier is turned off.
