What is hcxUpstrmPortSlotId?

This read-only Integer32 identifies the slot of the RX card that owns this upstream port, and the description notes that presently there is only one port per card. It rounds out the port's physical addressing alongside the shelf and port id attributes. For example, an NMS builds its topology view of upstream ports by combining hcxUpstrmPortSlotId with the shelf and port ids for each row in this table.
