I've actually tracked down the issue myself and wrote basically the same patch first :( Is there anything I can do (with my extremely limited phylink understanding) to help move this forward so other people don't have to suffer like I did?

That's weird, because I do have all the patches applied. I think this may have been broken by the pcs_inband_caps changes, because without the patch I'm just getting "autoneg setting not compatible with PCS", after which it bails, when it should really reconfigure the MAC instead.
