From 8997a10bfcad789d000debaac4cd85cd3db57997 Mon Sep 17 00:00:00 2001 From: Eric Kinzie Date: Tue, 1 Mar 2016 09:32:01 -0800 Subject: [PATCH] bonding: fix active slaves with no primary If the link state of a slave is "up" when added, it is added to the list of active slaves but, even if it is the only slave, is not selected as the primary interface. Generally, handling of link state interrupts selects an interface to be primary, but only if the active count is zero. This change avoids the situation where there are active slaves but no primary.
