All MII-capable PHYs should have a working PHYSID1 register. If it doesn't, something is broken.
It depends - I am not sure if there are PHYs which simply do not implement MDIO, but at least for ethernet switches, such chips do exist.
Right. We might need to add support for such PHYs, but just disabling the sanity check is far from enough.
In any case, the dm9161a PHY in question does implement MDIO, so it really should work without any modifications.
Maybe we can add the for cycle like in linux to check the phy addr?
