So this used to work. I have a 10G phy connected to the external MII
bus on a 6390. I wonder when this got broken? Supporting phy-handle is
old code, so when i added the external MII i don't think i needed to
change any generic code.

It could look like commit cd28a1a9baee7 ('net: dsa: fully divert PHY
reads/writes if requested') changed the of-case to use the mdio bus
associated with struct dsa_switch unconditionally.

Hi Martin

I think ds->phys_mii_mask is playing a role here. I need to add some
debug prints to my setup and see what is happening with my external
10G PHY.

This phy code is just too complex :-(
