+Subject: [PATCH] manager: allow controller activation if device is
+ deactivating
+
+When activating a port connection it will require the controller
+connection is active or a valid controller device candidate is available
+for activation.
+
+One of the conditions we consider for a controller device to be a valid
+candidate for the connection is that it is not active, therefore we
+should also consider as valid a device that is currently deactivating.
+Otherwise, we could fail during the port activation just because the
+deactivation of the controller device candidate didn't finish yet.
