Hi,
FYI, your patch has been queued to stable release 21.11.1
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/26/22. 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/26f2cc6490458d89864a35b6416ea450e79c1f78
Thanks.

Subject: [PATCH] net/bonding: fix promiscuous and allmulticast state
[ upstream commit ac5341f5f9bab7b87b1a71761c40d204a7e6ab86 ]
Currently, promiscuous or allmulticast state of bonding port will not be
passed to the new primary slave when active/standby switch-over. It
causes bugs in some scenario.
For example, promiscuous state of bonding port is off now, primary slave
(called A) is off but secondary slave(called B) is on.
Then active/standby switch-over, promiscuous state of the bonding port
is off, but the new primary slave turns to be B and its promiscuous
state is still on.
It is not consistent with bonding port. And this patch will fix it.
Fixes: 2efb58cbab6e ("bond: new link bonding library")
Fixes: 68218b87c184 ("net/bonding: prefer allmulti to promiscuous for LACP")
