[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/e44c18821c1fcf731f3ae7e369ff8c49524b1577

Thanks.

Kevin

Subject: [PATCH] net/bnxt: handle ring cleanup in case of error

[ upstream commit 75915b2b3c577ee5bb938c3f1ab6b51958c431a3 ]

In bnxt_alloc_mem(), after bnxt_alloc_async_ring_struct(),
any of the functions failure causes an error:

bnxt_hwrm_ring_free(): hwrm_ring_free nq failed. rc:1

Fix this by initializing ring->fw_ring_id to INVALID_HW_RING_ID
in bnxt_alloc_async_ring_struct().

Fixes: bd0a14c99f65 ("net/bnxt: use dedicated CPR for async events")
