If I use MII_PHY_ANY scan founds f= ollowing PHYs on miibus: There's been some discussions in the past about how to implement a switch PHY API for use by the variety of embedded switch devices out there. There's been a few attempts at it too. What I think may just be a good first step is to port over the Linux driver for it and instead of trying to make it appear as a multi-PHY device, just export a programming and status interface via sysctl. That at least gets the thing in the tree and functioning. Once we have a few devices in the tree and functioning, we'll be in a better position to have a discussion about how to represent it. There's a couple of dissenting views about how it should be implemented. I'd like to see some working code in the tree so some discussion can occur, rather than lots of dissent and no discussion. :) (The switch phy is the last remaining bit of the board support for a handful of boards too, so I'd really like to see it completed. :) Adrian
