[dpdk-stable] patch 'net/hns3: fix link speed when VF device 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/91f0c38c0d6561a1abca4ed00115e13829d327a4

Thanks.

Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit d1ced85a7e7a193051e96c2d34a8961a2e3f96d9 ]

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")
