The 'phy' parameter supplied to lan9303_phy_read/_write was sometimes a
DSA port number and sometimes a PHY address. This isn't a problem as
long as they are equal. But if the external phy_addr_sel_strap pin is
wired to 'high', the PHY addresses change from 0-1-2 to 1-2-3 (CPU,
slave0, slave1). In this case, lan9303_phy_read/_write must translate
between DSA port numbers and the corresponding PHY address.

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 reStructuredText 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.
