patch 'net/mlx5: set flow error for hash list create' 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 03/06/22. 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/383f7b7f800a445f546e977667334b9f1700814e

Thanks.

Kevin

Subject: [PATCH] net/mlx5: set flow error for hash list create

[ upstream commit 0c5d3e4cdf1bbc92d138bce1f98f0b260a10b8fc ]

While mlx5_hlist_create() failed, the rte_flow_error was not filled
with the corresponding error information.

This commit adds the missing rte_flow_error_set() for the failure case.

Fixes: f3020a331dca ("net/mlx5: optimize hash list table allocate on demand")
