[luca.boccassi@gmail.com]

Hi,

FYI, your patch has been queued to stable release 22.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/25. 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/29b4c863067a3708647ed76db684dfa966b60fd3

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: fix extra wait for link up

[ upstream commit 7c8cbd3c8ae0cec66fbd5acb89a62ee9742c70b4 ]

If the link auto-negotiation of the NIC is disabled,
or the flow control auto-negotiation is not supported,
it's unnecessary to wait for link establishment.

Fixes: 1f411e31a826 ("net/hns3: support flow control autoneg for copper port")
