Please apply the following patch series for qeth to netdev's net-next tree.

The netlink bridgeport attribute LEARNING_SYNC can be used to enable
qeth interfaces to report MAC addresses that are reachable via this
qeth interface to the attached software bridge via switchdev
notifiers SWITCHDEV_FDB_ADD_TO_BRIDGE and SWITCHDEV_FDB_DEL_TO_BRIDGE.

Extend this support of LEARNING_SYNC to the bridge to switchdev notifiers
SWITCHDEV_FDB_ADD_TO_DEVICE and SWITCHDEV_FDB_DEL_TO_DEVICE.

Add the capability to sync MAC addresses that are learned by a
north-facing, non-isolated bridgeport of a software bridge to
south-facing, isolated bridgeports. This enables the software bridge to
influence south to north traffic steering in hardware.
