[dpdk-stable] [PATCH] ethdev: update qfi definition

[Raslan Darawsheh <rasland@nvidia.com>]

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)

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.
