 
            Since the introduction of phylink-managed EEE support in the stmmac driver, EEE is now enabled by default, leading to issues on systems using the DP83867 PHY.
Did you do a bisect to prove this?
Fixes: 2a10154abcb7 ("net: phy: dp83867: Add TI dp83867 phy")
What has this Fixes: tag got to do with phylink?
I hope you have seen Russell is not so happy you claim phylink is to blame here...
