hello,

I'm sending a patch for Marvell 88e6060 driver.

Problem description:
Multiple APs with inter-AP roaming connected to different ports,
when station moves from one AP on one port to another AP on another port,
traffic flow breaks down because the learning table is not updated.


When Marvell's mac learning is enabled it drops all frames that
arrive from a MAC address that is on a different port at learning table.
It doesn't update learning table and breaks station roaming.


This patch disable Marvell 88E6060 hardware level mac learning and let it
be handled by the kernel.

Hi Anderson.

        /* Enable automatic address learning, set the address
         * database size to 1024 entries, and set the default aging
         * time to 5 minutes.
         */

  * time to 5 minutes.

  REG_WRITE(REG_GLOBAL, GLOBAL_ATU_CONTROL,
-   GLOBAL_ATU_CONTROL_ATUSIZE_1024 |
-   GLOBAL_ATU_CONTROL_ATE_AGE_5MIN);
+   GLOBAL_ATU_CONTROL_LEARNDIS);

Please update the comment as well.

       Thanks
