Subject: [dpdk-stable] [PATCH v2 2/2] ethdev: update qfi definition
Date: Tue, 30 Mar 2021 10:50:36 +0300
Message-ID: <20210330075036.6579-3-rasland@nvidia.com> (raw)
In-Reply-To: <20210330075036.6579-1-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) based on RFC 38415-g30

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.

Fixes: 346553db5bd1 ("ethdev: add GTP extension header to flow API")

Cc: stable@dpdk.org
