[dpdk-stable] patch 'net/nfp: fix RSS hash configuration reporting' has been queued to LTS release 18.11.10

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/25/20. 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-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/eb152c07bc9dc33964a229d183787c78fd06266f

Thanks.

Kevin.

Subject: [PATCH] net/nfp: fix RSS hash configuration reporting

[ upstream commit 198e745083b960d167bd769e2f81818c835f68b8 ]

Prior to this fix the NFP PMD implementation of the .rss_hash_conf_get
callback did not propagate the current hardware state of rss_hf back up
to the caller. Users of the hash_conf_get callback would receive an
incorrect representation of what the RSS configuration currently is in
hardware.

Fixes: 934e4c60fbff ("nfp: add RSS")
