/*
* The mv88e6xxx has three types of addresses: the smi bus address, the device
* address, and the register address. The smi bus address distinguishes it on
* the smi bus from other PHYs or switches. The device address determines
* which on-chip register set you are reading/writing (the various PHYs, their
* associated ports, or global configuration registers). The register address
* is the offset of the register you are reading/writing.
*
* When the mv88e6xxx is hardware configured to have address zero, it behaves in
* single-chip addressing mode, where it responds to all SMI addresses, using
* the smi address as its device address. This obviously only works when this
* is the only chip on the SMI bus. This allows the driver to access device
* registers without using indirection. When the chip is configured to a
* non-zero address, it only responds to that SMI address and requires indirect
* writes to access the different device addresses.
