/**
 * Create the output multicast packet based on the given input packet.
 * There are two approaches for creating outgoing packet, though both
 * are based on data zero-copy idea, they differ in few details:
 * First one creates a clone of the input packet, e.g - walk though all
 * segments of the input packet, and for each of them create a new packet
 * mbuf and attach that new mbuf to the segment (refer to rte_pktmbuf_clone()
 * for more details). Then new mbuf is allocated for the packet header
 * and is prepended to the 'clone' mbuf.
 * Second approach doesn't make a clone, it just increment refcnt for all
 * input packet segments. Then it allocates new mbuf for the packet header
 * and prepends it to the input packet.
 * Basically first approach reuses only input packet's data, but creates
 * it's own copy of packet's metadata. Second approach reuses both input's
 * packet data and metadata.
 * The advantage of first approach - is that each outgoing packet has it's
 * own copy of metadata, so we can safely modify data pointer of the
 * input packet. That allows us to skip creation if the output packet for
 * the last destination port, but instead modify input packet's header inplace,
 * e.g: for N destination ports we need to invoke mcast_out_pkt (N-1) times.
 * The advantage of second approach - less work for each outgoing packet,
 * e.g: we skip "clone" operation completely. Though it comes with a price -
 * input packet's metadata has to be intact. So for N destination ports we
 * need to invoke mcast_out_pkt N times.
 * So for small number of outgoing ports (and segments in the input packet)
 * first approach will be faster.
 * As number of outgoing ports (and/or input segments) will grow,
 * second way will become more preferable.
 *
 *  @param pkt
 *  Input packet mbuf.
 *  @param use_clone
 *  Control which of the two approaches described above should be used:
 *  - 0 - use second approach:
 *    Don't "clone" input packet.
 *    Prepend new header directly to the input packet
 *  - 1 - use first approach:
 *    Make a "clone" of input packet first.
 *    Prepend new header to the clone of the input packet
 *  @return
 *  - The pointer to the new outgoing packet.
 *  - NULL if operation failed.
