patch 'net/hns3: fix double decrement of secondary count' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/26/22. 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/2b7587ea997fd4fd76d6d9d33e5ac564858a3b37

Thanks.

Kevin

Subject: [PATCH] net/hns3: fix double decrement of secondary count

[ upstream commit c687877595ed7e287f3634d23736ff6400ad25af ]

The "secondary_cnt" indicates the number of secondary processes on an
Ethernet device. But the variable is double subtracted when detach the
device in secondary processes.

Fixes: ff6dc76e40b8 ("net/hns3: refactor multi-process initialization")
