*
* DESCRIPTION
*	The MAD Wrapper object encapsulates the information needed by the
*	OpenSM to manage individual MADs.  The OpenSM allocates one MAD Wrapper
*	per MAD.
*
*	The MAD Wrapper is not thread safe, thus callers must provide
*	serialization.
*
*	This object should be treated as opaque and should be
*	manipulated only through the provided functions.
