patch 'net/bonding: fix link status callback stop' 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 11/08/23. 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/6b396dceec44c55e02173c5d4e4ed087ec883dc2

Thanks.

Kevin

Subject: [PATCH] net/bonding: fix link status callback stop

[ upstream commit 615bd385b93e89e062b4e134e9cc09a79289a0f6 ]

If a bonding port gets released, a link status alarm callback still
referenced the ethdev port that may be reused later.
Cancel this callback when stopping the port.

Bugzilla ID: 1301
Fixes: a45b288ef21a ("bond: support link status polling")
