+Subject: [PATCH] device: start IP configuration when master carrier goes up
+
+If the master has no carrier in act_stage3_ip6_config_start(), we set
+IP state WAIT and wait until carrier goes up before starting IP
+configuration.
+
+However, in carrier_changed() if the device state is ACTIVATED we only
+call nm_device_update_dynamic_ip_setup(), which just restarts DHCP if
+it was already running.
+
+Let's also ensure that we start IP configuration if the IP state is
+WAIT.
+
