I'll look at what we can do for this today.

Hey folks, don't really want to necrobump this, but the original hack patch is the only way I can get my weirdo Realtek (noticing a pattern here) GPON modem-on-a-stick to probe at 2500base-x on a BPi-R4. 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?

There were two issues that were identified. The first was that when in
2500Base-X mode, the PCS wasn't reporting link-up. That was addressed
by the patch series:

Z4TbR93B-X8A8iHe@shell.armlinux.org.uk

then, the replacement for Eric's patch was:

E1tYhxp-001FHf-Ac@rmk-PC.armlinux.org.uk

So the problem should be solved with these applied, as when the PHY is
attached, "changed" will always be true, which is in effect what Eric's
patch was doing, but in a cleaner way.

Please confirm that you have all six patches applied.

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.
