This feature enable queue regions configuration for RSS in PF/VF, so

types can be separated to different queues in different queue
regions.This patch can set queue region range, it include queue number
in a region and the index of first queue.
This patch enable mapping between different priorities (UP) and
different traffic classes.It also enable mapping between a region
index and a sepcific flowtype(PCTYPE).It also provide the solution of
flush all configuration about queue region the above described.

Hi Wei,

I wonder if this can be implemented using rte_flow, instead of PMD specific
API?

And if not, what is missing in rte_flow for this?

Yes, at first I have plan to use rte_flow to implement this feature.
But there are many opposition for this, for example, this  feature is only support by i40e but not igb/ixgbe
From hardware capacity, not all NIC. So, private API is selected.

I guess rte_flow headers needs to be updated for this support, how big
that update, what is missing in rte_flow for this?

Even this is only for i40e, rte_flow can be an option. I believe this
increases the usability of the feature for the driver.
