The 88e6250 (as well as 6220, 6071, 6070, 6020) do not support multi-chip (indirect) addressing. However, one can still have two of them on the same mdio bus, since the device only uses 16 of the 32 possible addresses, either addresses 0x00-0x0F or 0x10-0x1F depending on the ADDR4 pin at reset [since ADDR4 is internally pulled high, the latter is the default]. In order to prepare for supporting the 88e6250 and friends, introduce mv88e6xxx_info::dual_chip to allow having a non-zero sw_addr while still using direct addressing.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
