So does this mean this patch series does allow packets to flow between
ports, not just to the CPU?

That is a fundamental part of DSA, switchdev, linux. netdev interfaces
are separated by default. If this is not true, you should add a big
fat warning to the patchset indicating how it is broken and what the
plan is to fix it.
