/**
 * @brief
 *   Used by a 'host' to enable the reception/listening of packets for a specific
 *   multicast group
 *
 *  For each socket on which IPMulticastListen has been invoked, the
 *  system records the desired multicast reception state for that socket.
 *  That state conceptually consists of a set of records of the form:
 *
 *     (interface, multicast-address, filter-mode, source-list)
 *
 *  The socket state evolves in response to each invocation of
 *  IPMulticastListen on the socket, as follows:
 *
 *  o If the requested filter mode is INCLUDE *and* the requested source
 *    list is empty, then the entry corresponding to the requested
 *    interface and multicast address is deleted if present.  If no such
 *    entry is present, the request is ignored.
 *
 *  o If the requested filter mode is EXCLUDE *or* the requested source
 *    list is non-empty, then the entry corresponding to the requested
 *    interface and multicast address, if present, is changed to contain
 *    the requested filter mode and source list.  If no such entry is
 *    present, a new entry is created, using the parameters specified in
 *    the request.
