Ethernet probing should only be done, when the device is really accessed (e.g. 
by using tftp commands). I know that the current implementation of the 
designware ethernet driver does this probing (PHY link negotiation etc) 
unconditionally at startup.

I have a patch in my queue that changes the designware driver to only start 
probing/auto-negotiating once its really used. I'll rebase my patch on top of 
your designware rework patches, once they are approved.

With this patch, this patch here should be unnecessary. At least when reading 
the patch description above.

So is this patch still needed, after my designware net driver rework?
