|
* 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.
