* P4080DS can be configured in many different ways, supporting a number
* of combinations of ethernet devices and phy types. In order to
* have just one device tree for all of those configurations, we fix up
* the tree here. By default, the device tree configures FM1 and FM2
* for SGMII, and configures XAUI on both 10G interfaces. So we have
* a number of different variables to track:
*
* 1) Whether the device is configured at all. Whichever devices are
* not enabled should be disabled by setting the "status" property
* to "disabled".
* 2) What the PHY interface is. If this is an RGMII connection,
* we should change the "phy-connection-type" property to
* "rgmii"
* 3) Which PHY is being used. Because the MDIO buses are muxed,
* we need to redirect the "phy-handle" property to point at the
* PHY on the right slot/bus.
