patch 'net/hns3: fix ignored reset event' has been queued to stable release 21.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/12/23. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/0dece2892b8a59d3fd4dbca5f9ea3a96e2b13837

Thanks.

Kevin

Subject: [PATCH] net/hns3: fix ignored reset event

[ upstream commit 4c40006c4b6b3c567185c84d60535752c9f7ea3d ]

The code logic that only new reset whose level is higher than old
reset level will be addressed is added in 'hns3_detect_reset_event()',
in fixed commit.

When the new reset is detected and the old reset level is
HNS3_NONE_RESET this reset will be ignored. This patch fix it.

Fixes: 5be38fc6c0fc ("net/hns3: fix multiple reset detected log")
