Florian Fainelli says:
====================
net: dsa: support PHY reads/writes diversion
This patch series completes the PHY reads/writes diversion when we need to use
the slave MII bus provided by DSA and the underlying switch drivers to
implement the real PHY reads and writes. This is particularly useful when they
are conflicting MDIO bus addresses as in the case of multiple Broadcom switches
connected to each other (internal and external, or just external).
