Hi,

FYI, your patch has been queued to stable release 20.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/23/23. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/943d18fcd75414213bb4a1a5fbca4ee5cb165871

Thanks.

Luca Boccassi

Subject: [PATCH] net/ipn3ke: fix thread exit

[ upstream commit d8f8e928a7ba23283300b1b80259d0c102348005 ]

Thread does not exit after driver is removed. When there is no
more representor exist, the variable 'num' will be 0 and thread
can exit safely at this time.

Fixes: 70d6b7f550f4 ("net/ipn3ke: add representor")
