Oleksij Rempel says: ==================== net: phy: microchip: LAN88xx reliability fixes This patch series improves the reliability of the Microchip LAN88xx PHYs, particularly in edge cases involving fixed link configurations or forced speed modes. Patch 1 assigns genphy_soft_reset() to the .soft_reset hook to ensure that stale link partner advertisement (LPA) bits are properly cleared during reconfiguration. Without this, outdated autonegotiation bits may remain visible in some parallel detection cases. Patch 2 restricts the 100 Mbps workaround (originally intended to handle cable length switching) to only run when the link transitions to the PHY_NOLINK state. This prevents repeated toggling that can confuse autonegotiating link partners such as the Intel i350, leading to unstable link cycles. Both patches were tested on a LAN7850 (with integrated LAN88xx PHY) against an Intel I350 NIC. The full test suite - autonegotiation, fixed link, and parallel detection - passed successfully. ==================== Link: https://patch.msgid.link/20250709130753.3994461-1-o.rempel@pengutronix.de 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 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.
