patch 'ethdev: fix Rx queue telemetry memory leak on failure' 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/c935f2719dd828b22c0b2cd40eec2d65074cda28

Thanks.

Kevin

Subject: [PATCH] ethdev: fix Rx queue telemetry memory leak on failure

[ upstream commit 52b49ea06ffb2cfbef8fe9578149f1e2dba99e89 ]

In eth_dev_handle_port_info() allocated memory for rxq_state,
we should free it when error happens, otherwise it will lead
to memory leak.

Fixes: 58b43c1ddfd1 ("ethdev: add telemetry endpoint for device info")
