patch 'net/hns3: fix fully use hardware flow director table' has been queued to stable release 23.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/10/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=50a97b8bc45fe9f2b1ba934029eaac251c146ae6

Thanks.

Subject: [PATCH] net/hns3: fix fully use hardware flow director table
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit b8e60c33168a2999604c17322dd0198a6746428f ]

The hns3 driver checks whether the flow rule is repeatedly inserted
based on rte_hash. Currently, the rte_hash extendable bucket table
feature is not enabled. When there are many hash conflicts, the hash
table space cannot be fully used. So the flow rule maybe cannot be
inserted even if the hardware flow director table there are still free.
This patch fix it by enabling the rte_hash extensible bucket table
feature.

Fixes: fcba820d9b9e ("net/hns3: support flow director")
