patch 'net/hns3: fix flushing multicast MAC address' has been queued to stable release 21.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/08/23. 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/7690a37723502aced124c8e573a502121c55ca1f

Thanks.

Kevin

Subject: [PATCH] net/hns3: fix flushing multicast MAC address

[ 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")
