From de79059ecd7cd650f3788ece978a64586921d1f1 Mon Sep 17 00:00:00 2001 From: Aji Srinivas Date: Wed, 7 Mar 2007 16:10:53 -0800 Subject: [BRIDGE]: adding new device to bridge should enable if up One change introduced by the workqueue removal patch is that adding an interface that is up to a bridge which is also up does not ever call br_stp_enable_port(), leaving the port in DISABLED state until we do ifconfig down and up or link events occur. The following patch to the br_add_if function fixes it. This is a regression introduced in 2.6.21. Submitted-by: Aji_Srinivas@emc.com Signed-off-by: Stephen Hemminger Signed-off-by: David S.
