The Marvell L2 switches which DSA supports have 8K FDB/MDB entries. So
maybe 1024 is a bit low?
How big is an FDB entry? Even an OpenWRT/LEDE class devices with 512MB
RAM can probably support 1MB of RAM for FDB entries.

DSA does not maintain synchronisation between the hardware tables and
the software tables. So no cloning. We expect both bridges to perform
learning based on the frames. This means we should be able to handle
one bridge flooding because its table is full, while the other has an
entry and forwards out the correct port.
