commit cee4bd16c3195a701be683f7da9e88c6e11acb73 upstream.
Dev can be renamed also while up for supported device. We currently wrongly clear the NETDEV_LED_MODE_LINKUP flag on NETDEV_CHANGENAME event.
Fix this by rechecking if the carrier is ok on NETDEV_CHANGENAME and correctly set the NETDEV_LED_MODE_LINKUP bit.
