- 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.
