I will measure the throughput with "alloc_ordered_workqueue(NAME,
WQ_HIGHPRI, ...)" to see if WQ_HIGHPRI works with alloc_ordered_workqueue.
Thanks for the suggestion.

Yeah, I think the comment is outdated. If it doesn't work as expected, please
let me know.
It works as expected. With alloc_oredered_workqueue(..., WQ_HIGHPRI,
...), the nice value is -20 and throughput result with 43455(11ac) on 1
core 1.6 Ghz platform is
Without WQ_HIGGPRI TX/RX: 293/301 (mbps)
With WQ_HIGHPRI TX/RX: 293/321 (mbps)
