Hi,
FYI, your patch has been queued to stable release 20.11.1
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/14/21. So please
shout if anyone has objections.
Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.
Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable
This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/f3bf966edc393ada2b7c1eb621e9452598d5240f
Thanks.

Subject: [PATCH] doc: fix mark action zero value in mlx5 guide
[ upstream commit b8ee0a16cb844027495968941a101f37964073cc ]
The zero value in flow MARK action is reported in Rx datapath
as tagged with zero FDIR ID. Once packet is marked in flow engine
it will be always reported as tagged. For metadata only the zero
value means there is "no metadata" in the packet and the metadata
flag is not set for the case.
Fixes: 3ceeed9f7855 ("doc: update flow mark action in mlx5 guide")
