Well, you need to apply all the patches I've sent you.

v3 is slightly different and you need the patch for the board file.
You need also the patches I've sent you privately.

I've tried both the old and the new (separate file) way of doing this.  Our EMAC does work fine, as does our SMSC, except our SMSC does not store a MAC address.  They just do not work together.  One or the other must be disabled (commented out of the code) or neither work.

The patch I've sent you solves exactly that...

Yes, there were several changes made to MDIO framework and how the whole thing is handled.
