Sorry, not been following this patch series.

One thing which might help here. Russell once said it should be
possible to use phylink with pcs to pcs links, rather than use
fixed-link. You then get all the phylink machinery, which might
trigger the pcs negotiation and get your link up?

I don't know of any board which actually does this, so i've no idea if
it really does work.
