I know we are very close to v4.10. But i don't think these changes
alone make the 6390 work properly. It appears that we still have:

       if (mv88e6xxx_6352_family(chip) || mv88e6xxx_6351_family(chip) ||
            mv88e6xxx_6165_family(chip) || mv88e6xxx_6097_family(chip) ||
            mv88e6xxx_6320_family(chip) || mv88e6xxx_6341_family(chip)) {
                /* Port ATU control: disable limiting the number of
                 * address database entries that this port is allowed
                 * to use.
                 */
                err = mv88e6xxx_port_write(chip, port, PORT_ATU_CONTROL,
                                           0x0000);
                /* Priority Override: disable DA, SA and VTU priority
                 * override.
                 */
                err = mv88e6xxx_port_write(chip, port, PORT_PRI_OVERRIDE,
                                           0x0000);
                if (err)
                        return err;
        }

to deal with. I have been working on 6390 for a long time, and would
like to see it working properly, but i'm not happy with the
non-obvious changes here, and the structure of these patches.

Please take your time to do this right. Lots of small patches, which
are obviously correct.
