+Subject: [PATCH] Fix process_link_changes handling 'up' interfaces
+
+b7f1d9b04212 refactored process_link_changes with helper methods to get
+the interface driver name and MAC address. This new code introduced a
+regression where it's possible for an interface in the up state to be
+included in the changelist by its MAC address.
+
+This patch restores the previous behaviour, skipping interfaces that
+don't have driver_name set.
+
