What do you think renaming:
i40e_region_info -> i40e_queue_region_info
i40e_queue_region_info -> i40e_queue_regions

Displaying is not always very useful in API level.
What do you think get fills the rss_region_conf with current device
settings and return back to the caller?

These are in public header now.
Can you please use same namespace for all ops.
It can be "RTE_PMD_I40E_RSS_QUEUE_REGION_"

Can you please be consistant in using public names.
There are:
rss_region
queue_region
rss_queue_region
Also there is confusion between using:
rte_i40e_
rte_pmd_i40e_

By defining port_id uint16_t, this patches becomes dependent to the
port_id update patchset, please clarify this in cover letter.
