Considering that you also have the option of setting ds->assisted_learning_on_cpu_port = true and this will have less false positives, what are the reasons why you did not choose that approach?
You're right. Hardware learning on CPU port does have some limitations. I have been testing a multi CPU ports patch, and assisted learning has to be used, because FDB entries should be installed like multicast ones, which point to all CPU ports.
