Did you try adding a sleep between mausezahn and the FDB dump? At least
that is what learning_test() is doing. It is possible that the packet is
not sent / processed fast enough for the bridge to learn it before the
dump.

Not in a generic forwarding test. Maybe in
tools/testing/selftests/drivers/net/dsa/

My preference would be to get as much tests as possible in
tools/testing/selftests/net/forwarding/bridge_locked_port.sh.

I'm not sure which tests you are planning for mv88e6xxx, but we can pass
/ fail test cases based on the flags we observe in the FDB dump. For
example, if the entry has the "sticky" flag, then the expectation is
that the roaming test will fail. Otherwise, it should pass.
