net: ethtool: Introduce a command to list PHYs on an interface
As we have the ability to track the PHYs connected to a net_device
through the link_topology, we can expose this list to userspace. This
allows userspace to use these identifiers for phy-specific commands and
take the decision of which PHY to target by knowing the link topology.
Add PHY_GET and PHY_DUMP, which can be a filtered DUMP operation to list
devices on only one interface.
