For that we have what we need with phy_link_topology, as each PHY has
its index, we should be good to go in that regard hopefully :)  

So depth would be local to a component? We could have two PHY
components, each with a different index, and depth = 0?

I _think_ Jakub's depth was more at a global level? But then it would
need to be passed down as we do the enumeration.

Oh, sorry, I responded without reading the whole discussion :)
No, I imagined the depth would be within a single component, 
so under control of a single driver (instance). The ordering
between components should be defined by PHY topology etc so
it's outside of the loopback config.
