I'm pretty sure HOTPLUG is only used when the interface ITSELF is attached to the system at runtime, not the cable, and MANAGED isn't used at all. If you set NM_CONTROLLED=no then the configuration will be loaded only if the system starts the "network" service and the configuration will not change on link up/link down. Otherwise, you need to check the messages log file for information from NetworkManager. dmesg will not tell you what you need to know.
