Detailed Description

Where this device sits in the ring (ENI Slave/PreviousPort).

Names the port of the upstream device that this one is plugged into, which is how a master learns the physical layout and not only the logical order. A device may carry several: the one it is actually connected to has selected set, and any other port it could be moved to without changing the order of the devices may be listed alongside with selected clear.

The element is absent for the first device on the bus, which has no previous device.
