Hi,

FYI, your patch has been queued to stable release 20.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/25/23. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/08e0d5d703e00d9e0205f14a04dc91a94cb06f3d

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: fix warning on flush or destroy rule

[ upstream commit a7bf2789168c8d49ca4dec5bb7bb0b3f765fc1bd ]

Although flow rules will no longer be used when user flush all rules
or destroy a rule a warning is generated like:
"modified RSS types based on hardware support, requested:0x137f83fffc
configured:0x3ffc".

Prevent warning for flush or destroy rule case.

Fixes: ec674cb742e5 ("net/hns3: fix flushing RSS rule")
