From: Matthijs Kooijman <matthijs@...in.nl> Date: Mon, 31 Oct 2011 15:53:13 +0100 > 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 <matthijs@...in.nl> Applied, thanks. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
