  This attribute is remained for compatible purpose. It is not recommended to

  use it in new code.



- port-idx-in-ae: is the index of port provided by AE.

  In NIC mode of DSAF, all 6 PHYs of service DSAF are taken as ethernet ports

  to the CPU. The port-idx-in-ae can be 0 to 5. Here is the diagram:

  In Switch mode of DSAF, all 6 PHYs of service DSAF are taken as physical

  ports connected to a LAN Switch while the CPU side assume itself have one

  single NIC connected to this switch. In this case, the port-idx-in-ae

  will be 0 only.
