patch 'app/testpmd: fix port status of bonding slave device' has been queued to stable release 21.11.2

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/22. 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/0dd479b1a1df56292b58b4b8983c94aac5bfb5f7

Thanks.

Kevin

Subject: [PATCH] app/testpmd: fix port status of bonding slave device

[ upstream commit e46372d7b082706718bb17981ae632e4e4d56414 ]

Starting or stopping a bonded port also starts or stops all active slaves
under the bonded port. If this port is a bonded device, we need to modify
the port status of all slaves.

Fixes: 0e545d3047fe ("app/testpmd: check stopping port is not in bonding")
