Yeah, but why would I want to? If you connect your MAC to any 5 PHYs my statement still stands, if directly to MII you don't need any PHY stuff at all, because link is always ON and speed/duplex is fixed. In fact, we use different switch chips connected to PPC4xx directly. In this situation, in my NAPI IBM EMAC driver I just have special "PHY-less" case which is trivial "fixed settings" one. And all this PHY lib is completely unneeded bloat. -- Eugene
