patch 'net/bnxt: fix RSS action' has been queued to stable release 21.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/30/22. 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/821dd9cd433bad28ee71e7656eb5acfe41af7aa4

Thanks.

Kevin

Subject: [PATCH] net/bnxt: fix RSS action

[ upstream commit 202a1711a1d318d97ee1d3cb718fc3fcf6ee2dad ]

Specifying a subset of Rx queues created by the application in
the "flow create" command is invalid.
User must either specify all Rx queues created or no queues.

Also removed a wrong comment as RSS action will not be supported
if user or application specifies MARK or COUNT action.

Fixes: 239695f754cb ("net/bnxt: enhance RSS action support")
