The pause settings reported by the PHY should also be applied to the GMII port status override otherwise the switch will not generate pause frames towards the link partner despite the advertisement saying otherwise.

Is this correct? phydev->pause and phydev->asym_pause keep the Pause and Asym_Pause bits advertised by the link partner. In other words, in this manual resolution you are ignoring what the local switch port has advertised.
linkmode_resolve_pause() is not used yet outside of phylink, but should help here.
