Parthiban Veerasooran says: ==================== Fixes on the Microchip's LAN865x driver This patch series includes two bug fixes for the LAN865x Ethernet MAC-PHY driver: 1. Fix missing transmit queue restart on device reopen This patch addresses an issue where the transmit queue is not restarted when the network interface is brought back up after being taken down (e.g., via ip or ifconfig). As a result, packet transmission hangs after the first down/up cycle. The fix ensures netif_start_queue() is explicitly called in lan865x_net_open() to properly restart the queue on every reopen. 2. Fix missing configuration in the Microchip LAN865x driver for silicon revisions B0 and B1, as documented in Microchip Application Note AN1760 (Rev F, June 2024). These revisions require the MAC to be configured for timestamping at the end of the Start of Frame Delimiter (SFD) and the Timer Increment register to be set to 40 ns, corresponding to a 25 MHz internal clock. Both patches address issues introduced with the initial driver support and are marked with the appropriate Fixes: tag. ==================== Link: https://patch.msgid.link/20250818060514.52795-1-parthiban.veerasooran@microchip.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 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.
