> The dpaa2-eth driver now has support for connecting to its associated PHY

> The notable change is that now, the DPMAC is not a separate driver, and
> communication between the DPMAC and DPNI no longer happens through
> firmware. Rather, the DPMAC is now a set of API functions that other
> net_device drivers (DPNI, DPSW, etc) can use for PHY management.
> 
> The change is incremental, because the DPAA2 architecture has many modes of
> connecting net devices in hardware loopback (for example DPNI to DPNI).
> Those operating modes do not have a DPMAC and phylink instance.
> 
> The documentation patch provides a more complete view of the software
> architecture and the current implementation.
