Hi,

FYI, your patch has been queued to stable release 22.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/24. 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://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/e0da7a253dbd6dac1cba895d81742a50313e44fc

Thanks.

Luca Boccassi

Subject: [PATCH] net/cnxk: fix promiscuous state after MAC change

[ upstream commit 5f1bce00fddffc63e5634891df2b02859c010944 ]

If promiscuous mode is enabled and default MAC address is set
again then promiscuous mode gets disabled in hardware.

This change will restore promiscuous behavior after configuring
default MAC address.

Fixes: 5fe86db2a0dd ("net/cnxk: support MAC address set")
