/**

* RTE Port for IPv4 Reassembly
*
* This port is built on top of pre-initialized single producer rte_ring. In
* order to minimize the amount of packets stored in the ring at any given
* time, the IP reassembly functionality is executed on ring write operation,
* hence this port is implemented as an output port. A regular ring_reader port
* can be created to read from the same ring.
*
* The packets written to the ring are either complete IP datagrams or IP
* fragments. The packets read from the ring are all complete IP datagrams,
* either jumbo frames (i.e. IP packets with length bigger than MTU) or not.
* The complete IP datagrams written to the ring are not changed. The IP
* fragments written to the ring are first reassembled and into complete IP
* datagrams or dropped on error or IP reassembly time-out.
