I would need more context here. What needs to be fixed?
I think we had several attempts, at the phylib days, to have this part of the driver behave correctly, so providing us more insight will help understand what is going wrong now. For instance, is it related to the patch that converts the driver to the phylink interface done by this patch in net-next "net: macb: convert to phylink"?

You mean we don't need to parse this phandle anymore because it's better handled by phylink_of_phy_connect() below that takes care of the fixed-link case? If yes, then telling it in commit message is worth it...

Why modifying this?
