The CPSW switch can act as Dual EMAC by segregating the switch ports

Following CPSW components will be common for both the interfaces.
* Interrupt source is common for both eth interfaces
* Interrupt pacing is common for both interfaces
* Hardware statistics is common for all the ports
* CPDMA is common for both eth interface
* CPTS is common for both the interface and it should not be enabled on
both the interface as timestamping information doesn't contain port
information.
Constrains
* Reserved VID of One port should not be used in other interface
which will
enable switching functionality
* Same VID must not be used in both the interface which will enable

Shouldn't this be:-

^^^^^^^^^^
... so we pick each VLAN id from the individual slaves ?
Good catch, will send a fixup patch for this.
