Hello all,

I just upgraded my arm64 SynQuacer box to 5.8.16 and lost all network
connectivity.

Hi Ard

Please could you point me at the DT files.

This box has a on-SoC socionext 'netsec' network controller wired to
a Realtek 80211e PHY, and this was working without problems until
the following commit was merged

It could be this fix has uncovered a bug in the DT file. Before this
fix, if there is an phy-mode property in DT, it could of been ignored.
Now the phy-handle property is correctly implemented. So it could be
the DT has the wrong value, e.g. it has rgmii-rxid when maybe it
should have rgmii-id.

This is an ACPI system. The phy-mode device property is set to 'rgmii'
