[dpdk-stable] patch 'net/hns3: fix link speed when port is down' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/180a37c3ef268f6f1c31b8948bf04f6e9e4281bc

Thanks.

Subject: [PATCH] net/hns3: fix link speed when port is down
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 230d4940ed8e4fc0138fab2fdb2087553b8465dd ]

When the port is link down state, it is meaningless to display the
port link speed. It should be an undefined state.

Fixes: 59fad0f32135 ("net/hns3: support link update operation")
