patch 'net/hns3: fix never set MAC flow control' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=2a7aef1dd0c51b04b7f36fea94ece654ba6893a0

Thanks.

Subject: [PATCH] net/hns3: fix never set MAC flow control
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 2350eb39f337f9e8d798f8dd1d658834e3981e9e ]

When some hardware and firmware support speed auto-negotiation
but do not support flow control auto-negotiation, driver can
never successfully set MAC flow control by flow_ctrl_set() API.
So only tell user driver doesn't support flow control autoneg
when user enable it.

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