Re: [PATCH net-next v2 01/10] net: phy: add "internal" PHY mode

On some systems, the PHY can be internal, in the same package as the
Ethernet MAC, and still be responding to a specific address on the MDIO
bus, in that case, the Ethernet MAC might need to know about it to
properly configure a port multiplexer to switch to an internal or
external PHY. Add a new PHY interface mode for this and update the
Device Tree of_get_phy_mode() function to look for it.

Changes since v1:
- rebased against lastest net-next master branch

This is over-engineering.

The only thing that even uses this value is phy_is_internal(), and
the only user of phy_is_internal() is the generic PHY layer ethtool
operation for get-settings.

The PHY layer already has a place to indicate whether a PHY is
internal or not, overriding that using the PHY mode is trouble
waiting to happen.

Please, just provide some way to propagate this device tree property
into phy->is_internal.
