50  * Functions to support creating, modifying, destroying, querying the
51  * state of and changing the state of NCP (Network Configuration Profiles)
52  * and the NCUs (Network Configuration Units) that are contained in those
53  * NCP objects.  An NCP is simply a container for a set of NCUs which represent
54  * the datalink and interface configuration preferences for the system.
55  * An NCP can consist a set of prioritized link NCUs, e.g. wired links preferred
56  * over wireless, a set of manually enabled/diasbled NCUs, or a combination
57  * of both. Interface NCUs inherit activation from their underlying links,
58  * so if wired is preferred over wireless and a cable is plugged in,
59  * the wired link NCU will be active, as will the IP interface NCU above it.
