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?
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 header.
There is already a deprecation notice for using protocol header directly in the 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 rte_flow struct.
