Some DPDK applications wrongly assume these requirements:
- no hotplug, i.e. ports are never detached
- all allocated ports are available to the application
Such application iterates over ports by its own mean.
The most common pattern is to request the port count and
assume ports with index in the range [0..count[ can be used.
In order to fix this common mistake in all external applications,
the function rte_eth_dev_count is deprecated, while introducing
the new functions rte_eth_dev_count_avail and rte_eth_dev_count_total.

Use service cores for offloading event scheduling in case of
centralized scheduling instead of calling the schedule api directly.
This removes the dependency on dedicated scheduler core specified by
giving command line option --slcore.

This is a performance test case that aims at testing the following:
1. Measure the number of events can be processed in a second.
2. Measure the latency to forward an event.
The atq queue test functions as same as "perf_queue" test.
The difference is, it uses, "all type queue" scheme instead of separate
queues for each stage and thus reduces the number of queues required to
realize the use case and enables flow pinning as the event does not
move to the next queue.
Example command to run perf "all types queue" test:
sudo build/app/dpdk-test-eventdev --vdev=event_octeontx --\
--test=perf_atq --plcores=2 --wlcore=3 --stlist=p --nb_pkts=1000000000
