There are only two thread priorities in the enum rte_thread_priority: =
Normal and Real-time Critical.

I would like to poll ethdev counters, collect garbage and perform other =
jitter non-sensitive tasks in a control thread with lower priority than =
my ordinary control threads, so it will be preempted by any work ready =
for my ordinary control threads.

Which DPDK API am I supposed to use to assign this below-normal priority =
to my "background" control thread?

Or: Aren't we missing a priority like Linux' SCHED_BATCH?
