The Atheros AR8031 and AR8033 expose different registers for SGMII/Fiber as well as the copper side of the PHY depending on the BT_BX_REG_SEL bit in the chip configure register. The driver assumes the copper side is selected on probe, but this might not be the case depending which page was last selected by the bootloader. Notably, Ubiquiti UniFi bootloaders show this behavior. Select the copper page when probing to circumvent this. Signed-off-by: David Bauer <mail@david-bauer.net> Signed-off-by: David S.

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.
