On lan966x it is not allowed to have foreign interfaces under a bridge which already contains lan966x ports. So when a port leaves the bridge it would call switchdev_bridge_port_unoffload which eventually will notify the other ports that bridge left the vlan group but that is not true because the bridge is still part of the vlan group. Therefore when a port leaves the bridge, stop generating replays because already the HW cleared after itself and the other ports don't need to do anything else.
