41 * Segment an IPv4/TCP packet. This function doesn't check if the input
42 * packet has correct checksums, and doesn't update checksums for output
43 * GSO segments. Furthermore, it doesn't process IP fragment packets.
46 * The packet mbuf to segment.
48 * The max length of a GSO segment, measured in bytes.
50 * The increasing unit of IP ids.
52 * MBUF pool used for allocating direct buffers for output segments.
53 * @param indirect_pool
54 * MBUF pool used for allocating indirect buffers for output segments.
56 * Pointer array used to store the MBUF addresses of output GSO
57 * segments, when the function succeeds. If the memory space in
58 * pkts_out is insufficient, it fails and returns -EINVAL.
60 * The max number of items that 'pkts_out' can keep.
63 * - The number of GSO segments filled in pkts_out on success.
64 * - Return -ENOMEM if run out of memory in MBUF pools.
65 * - Return -EINVAL for invalid parameters.
