Hi,
FYI, your patch has been queued to stable release 20.11.4
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/12/21. 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/288a450bb909e5e1acb8fc323cc555b3eb645f59
Thanks.

Subject: [PATCH] net/hns3: fix input parameters of MAC functions
Cc: Xueming Li <xuemingl at nvidia.com>
[ upstream commit 60a6b4a574cf3b9415c73c31173eb42deb5ca92b ]
When adding multicast and unicast MAC addresses, three descriptors and
one descriptor are required for querying or adding MAC VLAN table,
respectively. This patch uses the number of descriptors as input
parameter to complete this task to make the function more secure.
Fixes: 7d7f9f80bbfb ("net/hns3: support MAC address related operations")
