patch 'net/hns3: fix flushing multicast MAC address' has been queued to stable release 22.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/15/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=15b43a21b222f5e01d8ff11b0aa466b1110e8278

Thanks.

Subject: [PATCH] net/hns3: fix flushing multicast MAC address
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 49d1ab205b033b6131fb895b5e4d9ebc14081e51 ]

According rte_eth_dev_set_mc_addr_list() API definition,
support flush multicast MAC address if mc_addr_set is NULL
or nb_mc_addr is zero.

Fixes: 7d7f9f80bbfb ("net/hns3: support MAC address related operations")
