Shamelessly copy-pasted below.
Richard ===========================================================================
Add MII commands to the UEC driver. Note that once a UEC device is selected, any device on its MDIO bus can be addressed.

The last info I have on this patch is on this posting:

Hm... I vaguely recall seeing that, but it's more in Ben Warren's domain. He probably wasn't copied on the patch, either.
Yeah, looks like I missed that one. To answer your question, no. I won't be able to apply it until the weekend at the earliest, so for now please just apply the patch yourself.
Can you please post updated patches?
Thanks in advance.
Best regards,
Wolfgang Denk
