No, you do not miss - this is an issue. In fact MDIO bus was changed for numeric for gianfar-stuff, and has been remaining string for fs_enet. I think it makes sense to average this up, and will try to do that once will get 8349-mitx which is gianfar+ fixed user. The point is that fixed should be updated to numeric MDIO address encoding. This has to come through netdev, so I'll try to get it fixed by the next merge window. -- Sincerely, VitalyIdeally (for me anyway), we'd be able to pass some fixed phy information via the device tree, for example speed and duplexity. This way a board could, for example, connect to one switch via RvMII @100FD and another via GMII @1000FD. Having parameters as numeric limits this capability, but presumably a simple encoding scheme could be make it work. I'm sure you've already thought of this, though...
Yes, I was thinking about something like 0:1001 or 0:101 where 1 at the end respects duplexity. Putting it into devtree is good but we'll need to unify the interface first. -- Sincerely, Vitaly
