Heiner Kallweit says: ==================== r8169: improve RTL8168g PHY suspend quirk According to Realtek the ERI register 0x1a8 quirk is needed to work around a hw issue with the PHY on RTL8168g. The register needs to be changed before powering down the PHY. Currently we don't meet this requirement, however I'm not aware of any problems caused by this. Therefore I see the change as an improvement. The PHY driver has no means to access the chip ERI registers, therefore we have to intercept MDIO writes to the BMCR register. If the BMCR_PDOWN bit is going to be set, then let's apply the quirk before actually powering down the PHY. ==================== Link: https://lore.kernel.org/r/9303c2cf-c521-beea-c09f-63b5dfa91b9c@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
