[PATCH net-next] net: dsa: mv88e6xxx: fix 6185 hardware bridging

[Vivien Didelot]

The 88E6185 switch also has a MapDA bit in its Port Control 2 register.
When this bit is cleared, all frames are sent out to the CPU port.

Set this bit to rely on ATU hits and direct the frame out of the correct
ports, and thus enable hardware bridging.

Andrew, I sent this patch too fast. It requires a proper support of the
ATU in order to populate the FDB correctly. I send that soon.

David, please ignore this patch for the moment.

Thanks,
Vivien

Ok.
