Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/22/26. 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/94809d36ff5ecc076c930759c475269a188752f7

Thanks.

Luca Boccassi

Subject: [PATCH] net/dpaa: fix BMI xstats by ID

[ upstream commit 6809c99b85b931855439049b05ea37974a1a8bfb ]

In dpaa_xstats_get_by_id(), fman_if_bmi_stats_get_all() was called
with 'values' (the output array) instead of 'values_copy' (the
scratch buffer). This caused the BMI stats to overwrite already
computed xstat values and then the subsequent loop would copy
garbage from values_copy into the output.

Pass 'values_copy' as intended so that BMI stats are fetched into
the scratch buffer and then correctly indexed into 'values'.

Fixes: d2536b006d78 ("bus/dpaa: add port buffer manager stats")
