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

NAK, please use pipeline_atq/queue to test Rx->Tx performance.
Perf_atq/queue should only be used to test event device performance/latency such as
<event_src(CPU/Rx/timer)> -> worker.
