Hi,

FYI, your patch has been queued to stable release 22.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/26/24. 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/d69a8b5eb2badb1c7998948c4b80a96f5312dd03

Thanks.

Luca Boccassi

Subject: [PATCH] common/mlx5: remove unneeded field when modify RQ table

[ upstream commit 463e5abe09362f1d20d0ec99b5969549d51167d6 ]

The attribute "rqt_max_size" of the RQT(RQ table) context is only
needed by when creating a new one. When modifying an old one, there
is no need to set this attribute.

The firmware usually ignored this unneeded field. When enabling some
extra check, an error will be returned to prevent the code from
continuing to run.

In the meanwhile, this field will always be set to the maximal one
fetched from the capability without any change.  Removing the value
set and leave it to 0 will help to solve the potential failure.

Fixes: e1da60a8a6e9 ("common/mlx5: add DevX command to modify RQT")
