I confirmed with some internal contacts a few extra bits about questions about this from throughout the conversation. 1) This feature IS in the general Realtek driver for Windows, not a special Dell driver. 2) The feature only offered to the Realtek 8153-AD, no other Realtek chip will do it (even Realtek 8153-VB won't). 3) The feature is activated when a special "Docking" bit is set on the 8153-AD. 4) The feature is activated on all Realtek 8153-AD's on the host system with the docking bit set. So on Windows if two Dell docks were hooked up they would both have the same AUX MAC. So considering that I think it would make sense to only activate in those same special circumstances (RTL8153-AD, docking bit set, system has \\_SB.AMAC). I also feel this should stay in the Realtek driver as this as this implementation is very Realtek specific.
