[dpdk-dev,v3,03/17] app/test: eventdev link all queues before start
Checks
Commit Message
The software eventdev can lock-up if not all queues are
linked to a port. For this reason, the software evendev
fails to start if queues are not linked to anything.
This commit creates dummy links from all queues to port
0 in the eventdev setup function and start/stop test,
which would otherwise fail due to unlinked queues.

You can replace the for loop and pass NULL to link all the queues.
i.e rte_event_port_link(TEST_DEV_ID, 0, NULL, NULL, 0);
