       RTE Port for IPv4 Fragmentation

       This port is built on top of pre-initialized single consumer rte_ring. In order to minimize the amount of
       packets stored in the ring at any given time, the IP fragmentation functionality is executed on ring read
       operation, hence this port is implemented as an input port. A regular ring_writer port can be created to
       write to the same ring.

       The packets written to the ring are either complete IP datagrams or jumbo frames (i.e. IP packets with
       length bigger than provided MTU value). The packets read from the ring are all non-jumbo frames. The
       complete IP datagrams written to the ring are not changed. The jumbo frames are fragmented into several
       IP packets with length less or equal to MTU.
