and a set of worker lcores which are responsible for receiving the packets from the distributor and operating on them.
The model of operation is shown in the diagram below.

Distributor Core Operation
--------------------------
Using the process and returned_pkts API, the following application workflow can be used,
while allowing packet order within a packet flow -- identified by a tag -- to be maintained.

The flush and clear_returns API calls, mentioned previously,
are likely of less use that the process and returned_pkts APIS, and are principally provided to aid in unit testing of the library.
i.e. to save power at times of lighter load,
it is possible to have a worker stop processing packets by calling "rte_distributor_return_pkt()" to indicate that
it has finished the current packet and does not want a new one.
