33  * @brief
34  * Used by a 'host' to enable the reception/listening of packets for a specific
35  * multicast group
36  *
37  * For each socket on which IPMulticastListen has been invoked, the
38  * system records the desired multicast reception state for that socket.
39  * That state conceptually consists of a set of records of the form:
40  *
41  * (interface, multicast-address, filter-mode, source-list)
42  *
43  * The socket state evolves in response to each invocation of
44  * IPMulticastListen on the socket, as follows:
45  *
46  * o If the requested filter mode is INCLUDE *and* the requested source
47  * list is empty, then the entry corresponding to the requested
48  * interface and multicast address is deleted if present. If no such
49  * entry is present, the request is ignored.
50  *
51  * o If the requested filter mode is EXCLUDE *or* the requested source
52  * list is non-empty, then the entry corresponding to the requested
53  * interface and multicast address, if present, is changed to contain
54  * the requested filter mode and source list. If no such entry is
55  * present, a new entry is created, using the parameters specified in
56  * the request.
