[dpdk-stable] [PATCH 5/6] app/test-eventdev: Enhancing perf-atq packet flow

[Apeksha Gupta]

The event ethernet Tx adapter provides data path for the ethernet transmit
stage. Enqueue a burst of events objects supplied on an event device.

Fixes: 1eb10ad8db8 ("app/testeventdev: add perf all types queue worker")
