Do you have any comment on this? You resent the BR_PORT_MAB patches without even an ack that yes, mv88e6xxx will not support MAB being enabled on a bridge port, and will not reject the configuration either, and that's ok/intended. Do you think this is not true? Irrelevant? The "fix" (to implement offloading) might come in this development cycle, or it might not.
