From deede2fabe24e00bd7e246eb81cd5767dc6fcfc7 Mon Sep 17 00:00:00 2001 From: Matthijs Kooijman Date: Mon, 31 Oct 2011 04:53:13 +0000 Subject: [PATCH] vlan: Don't propagate flag changes on down interfaces. When (de)configuring a vlan interface, the IFF_ALLMULTI ans IFF_PROMISC flags are cleared or set on the underlying interface. So, if these flags are changed on a vlan interface that is not up, the flags underlying interface might be set or cleared twice. Only propagating flag changes when a device is up makes sure this does not happen. It also makes sure that an underlying device is not set to promiscuous or allmulti mode for a vlan device that is down. Signed-off-by: Matthijs Kooijman Signed-off-by: David S.
