qfi field is 8 bits which represent single bit for
PPP (paging Policy Presence) single bit for RQI
(Reflective QoS Indicator) and 6 bits for qfi
(QoS Flow Identifier)

Can you please put a reference for above information?

Sure, will send in V2,

This update the doxygen format and the mask for qfi
to properly identify the full 8 bits of the field.

note: changing the default mask would cause different
patterns generated by testpmd.

By design requirement, rte_flow_item_* should start with the relevant

protocol

quoted

header.

There is already a deprecation notice for using protocol header directly in

the

quoted

rte_flow_item* [1] and Adrew/Ivan already fixed a few of them [2].

Your patch is not directly related on this, but since you are touching to the
flow_item, would you mind create a protocol struct for it first, and use it in
the "struct rte_flow_item_gtp_psc"?
So the protocol related update can be done in the protocol header, instead

of

quoted

rte_flow struct.

Sure, I can create the new protocol and use it , and will send in V2. But, wouldn't it cause any ABI breakage ?
