patch 'net/hns3: remove redundant RSS tuple field' has been queued to stable release 20.11.6

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/23/22. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/21c2dd60110b93d9c3bceb35bb9ae8f9610a3edd

Thanks.

Subject: [PATCH] net/hns3: remove redundant RSS tuple field
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit bfd0b54dc84f06183c8a13f75539f0f1dacb3c3e ]

The 'rss_tuple_fields' in struct struct hns3_rss_conf::rss_tuple_sets is
redundant. Because the enabled RSS tuple in PMD is already managed by
the 'types' in struct hns3_rss_conf::conf. This patch removes this
redundant variable.

Fixes: c37ca66f2b27 ("net/hns3: support RSS")
