Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/07/26. 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/c449428f9edf5ac543e329993cc5e0a1288d2fbf

Thanks.

Luca Boccassi

Subject: [PATCH] net/gve: fix DQO descriptor cleaning loop bound

[ upstream commit 831ea900d7b619ab0d11a03f68d94513aa059cac ]

gve_tx_clean_descs_dqo() loops on "while (--nb_descs)", which
processes one completion fewer than requested, and none when asked
for one.

Use a post-decrement so exactly nb_descs completions are processed.

Fixes: 4022f9999f56 ("net/gve: support basic Tx data path for DQO")
