274 * Create the output multicast packet based on the given input packet.
275 * There are two approaches for creating outgoing packet, though both
276 * are based on data zero-copy idea, they differ in few details:
277 * First one creates a clone of the input packet, e.g - walk though all
278 * segments of the input packet, and for each of them create a new packet
279 * mbuf and attach that new mbuf to the segment (refer to rte_pktmbuf_clone()
280 * for more details). Then new mbuf is allocated for the packet header
281 * and is prepended to the 'clone' mbuf.
282 * Second approach doesn't make a clone, it just increment refcnt for all
283 * input packet segments. Then it allocates new mbuf for the packet header
284 * and prepends it to the input packet.
285 * Basically first approach reuses only input packet's data, but creates
286 * it's own copy of packet's metadata. Second approach reuses both input's
287 * packet data and metadata.
288 * The advantage of first approach - is that each outgoing packet has it's
289 * own copy of metadata, so we can safely modify data pointer of the
290 * input packet. That allows us to skip creation if the output packet for
291 * the last destination port, but instead modify input packet's header inplace,
292 * e.g: for N destination ports we need to invoke mcast_out_pkt (N-1) times.
293 * The advantage of second approach - less work for each outgoing packet,
294 * e.g: we skip "clone" operation completely. Though it comes with a price -
295 * input packet's metadata has to be intact. So for N destination ports we
296 * need to invoke mcast_out_pkt N times.
297 * So for small number of outgoing ports (and segments in the input packet)
298 * first approach will be faster.
299 * As number of outgoing ports (and/or input segments) will grow,
300 * second way will become more preferable.
305 * Control which of the two approaches described above should be used:
306 * - 0 - use second approach:
307 * Don't "clone" input packet.
308 * Prepend new header directly to the input packet
309 * - 1 - use first approach:
310 * Make a "clone" of input packet first.
311 * Prepend new header to the clone of the input packet
313 * - The pointer to the new outgoing packet.
314 * - NULL if operation failed.
