patch 'net/null: fix Tx statistics accumulation' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/02/26. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/67aac277cc9b761d7915f17ba8bda90e26839845

Thanks.

Kevin

Subject: [PATCH] net/null: fix Tx statistics accumulation

[ upstream commit db55352a153328fb8dfc4d74c0578a7f1e1bd987 ]

The eth_stats_get() function incorrectly uses assignment (=) instead
of accumulation (+=) for opackets and obytes in the TX queue loop.
This causes only the last TX queue's statistics to be reported,
while the RX side correctly uses +=.

Fixes: 31326ce7f151 ("net/null: count all queues")
