That is really core of the problem here. We have no reliable description of the hardware. The datasheet often starts with a block diagram of the PHY package. Sometimes there is a product brief with the same diagram. We need that published. I'm not asking for the full data sheet, just the introductory text which gives a high level overview of what the hardware actually is. Then we can sketch out a high level Linux architecture for the PHY package. Andrew
