patch 'test/bonding: fix RSS test when disable RSS' 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 07/22/22. 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/1adbdac76c2277546bedfb664a37d6e7e5339721

Thanks.

Subject: [PATCH] test/bonding: fix RSS test when disable RSS
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 6496922368fe03be9ab4137f2d615dba1a766f39 ]

The "test_rss_lazy" test is used for testing bonding RSS functions
when bonded port disable RSS. Currently, this test case can update
RSS functions of bonded and slave port if bonded port turns off RSS.
It is unreasonable and has been adjusted to be non-updateable in
following patch:
"93e1ea6dfa99 ethdev: fix RSS update when RSS is disabled"

So this patch fixes this test code.

Fixes: 43b630244e7e ("app/test: add dynamic bonding RSS configuration")
