There is more than one logical change here. I suggest splitting it to
make review easier:
1. A patch allowing the bridge driver to install locked entries notified
from device drivers. These changes:
include/net/switchdev.h | 1 +
net/bridge/br.c | 4 ++--
net/bridge/br_fdb.c | 12 ++++++++++--
net/bridge/br_private.h | 2 +-
And the br_switchdev_fdb_populate() hunk
2. A patch allowing DSA core to report locked entries to the bridge
driver
3. A patch adding the new MAB flag to BR_PORT_FLAGS_HW_OFFLOAD
4. A patch allowing DSA core to propagate the MAB flag to device drivers

Not sure how this is related to the patchset.
