Hi,
FYI, your patch has been queued to LTS release 18.11.9
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/10/20. 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/02200202f5ea01c97c851395a0431b24025dcd28

Subject: [PATCH] net/mlx5: fix RSS enablement
[ upstream commit 0afac6dcca44dea15f23e93851b6e52f014a98e4 ]
PMD create some default control rules with RSS action
if it's not isolated mode.
However whether default control rules need to do RSS or not should be
controlled by device configuration, the mq_mode of rxmode configuration
in specific.
In another word, only when mq_mode is configured with ETH_MQ_RX_RSS_FLAG
set, then RSS is needed for default rules.
Fixes: c64ccc0eca2f ("mlx5: fix overwritten RSS configuration")
