XRAN fragmentation.
This function implements the application fragmentation of XRAN packets.
pkt_in | The input packet. |
pkts_out | Array storing the output fragments. |
mtu_size | Size in bytes of the Maximum Transfer Unit (MTU) for the outgoing XRAN datagrams. This value includes the size of the XRAN headers. |
pool_direct | MBUF pool used for allocating direct buffers for the output fragments. |
pool_indirect | MBUF pool used for allocating indirect buffers for the output fragments. |
