What is rlPhdStackMacAddr?

This read-only PhysAddress reports the base MAC address burned into this specific stack unit's hardware. An admin needs this to distinguish units at the hardware level, for example when configuring MAC-based access rules or when the stack's management MAC needs to be traced to its originating physical unit. For example, if the stack's overall management MAC address changes after a master failover, the admin checks this field on each unit to confirm which physical unit's MAC is now being used.
