Hi,

FYI, your patch has been queued to stable release 20.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/21/23. 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/e2ee086768ce210b5fb58c16051589641e6b09b0

Thanks.

Luca Boccassi

Subject: [PATCH] net/iavf: fix port stats clearing

[ upstream commit 57fc68cf11cf3ec49526d8a8eca98956d5b77989 ]

After VF reset, kernel driver may reuse the original VSI without reset its
stats. Call 'iavf_dev_stats_reset' during the initialization of the VF in
order to clear any statistics that may exist from the last use of the VF
and to avoid statistics errors.

Fixes: 22b123a36d07 ("net/avf: initialize PMD")
