patch 'net/ice: fix statistics' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=83ad87933a05f5eb8a51cd83cc90d7dbd40412d5

Thanks.

Subject: [PATCH] net/ice: fix statistics
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit a47ef8640a677a3973de48b8075f1fcd6a0ee68e ]

When the stats_get api is called for the first time in pmd, the offset
of the stats register is not recorded. That results in all the obtained
count values being 0.

This patch adds reset statistics before dev_init returning. That avoids
some noise being counted.

Fixes: 12443386a0b0 ("net/ice: support flex Rx descriptor RxDID22")
