[dpdk-dev] [PATCH v6 07/14] app/eventdev: add Tx service setup

Tue Jan 16 16:39:56 CET 2018
Setup one port event port for Tx and link the respective event queue.
Register the Tx function as a service to be called from a service core.
The Tx function dequeues the events from the event queue and transmits
the packet to its respective ethernet port.
