patch 'net/cnxk: fix RSS RETA table update' 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/d9af841e5a2ad902db734c152288eed0933463af

Thanks.

Kevin

Subject: [PATCH] net/cnxk: fix RSS RETA table update

[ upstream commit fe3833ed2222c369f9b60c0be520dee6e875dcdf ]

RSS reta table is corrupted during rte_eth_dev_rss_reta_update().
Fix it by restoring previous table entries before updating.

Fixes: 00242a687de6 ("net/cnxk: support RETA and RSS hash")
