/**
|
|
* Segment a tunneling packet with inner UDP/IPv4 headers. This function
|
|
* does not check if the input packet has correct checksums, and does not
|
|
* update checksums for output GSO segments. Furthermore, it does not
|
|
* process IP fragment packets.
|
|
*
|
|
* @param pkt
|
|
* The packet mbuf to segment.
|
|
* @param gso_size
|
|
* The max length of a GSO segment, measured in bytes.
|
|
* @param direct_pool
|
|
* MBUF pool used for allocating direct buffers for output segments.
|
|
* @param indirect_pool
|
|
* MBUF pool used for allocating indirect buffers for output segments.
|
|
* @param pkts_out
|
|
* Pointer array used to store the MBUF addresses of output GSO
|
|
* segments, when it succeeds. If the memory space in pkts_out is
|
|
* insufficient, it fails and returns -EINVAL.
|
|
* @param nb_pkts_out
|
|
* The max number of items that 'pkts_out' can keep.
|
|
*
|
|
* @return
|
|
* - The number of GSO segments filled in pkts_out on success.
|
|
* - Return 0 if it needn't GSO.
|
|
* - Return -ENOMEM if run out of memory in MBUF pools.
|
|
* - Return -EINVAL for invalid parameters.
