+ * 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.
