Hi,
FYI, your patch has been queued to stable release 21.11.4
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/28/23. 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/kevintraynor/dpdk-stable
This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/69d2be50d9ec4bbad7342d2bf00894b918150b0f
Thanks.
Kevin

Subject: [PATCH] net/hns3: fix config struct used for conversion
[ upstream commit 815c7db53167f7ee1573dca18fa7f889e44764d4 ]
When the type in 'struct rte_flow_action' is RTE_FLOW_ACTION_TYPE_RSS,
the 'conf' pointer references the 'struct rte_flow_action_rss' instead
of the 'struct hns3_rss_conf' in driver. But driver uses 'struct
hns3_rss_conf' to convert this 'conf' pointer to get RSS action
configuration.
In addition, RSS filter configuration is directly cloned to RSS filter
node instead of coping it after successfully setting to hardware.
Fixes: c37ca66f2b27 ("net/hns3: support RSS")
