Russell King says: ==================== net: pcs: xpcs: cleanups for clause 73 support This series cleans up xpcs code, moving much of the clause 73 code out of the driver into places where others can make use of it. Specifically, we add a helper to convert a clause 73 advertisement to ethtool link modes to mdio.h, and a helper to resolve the clause 73 negotiation state to phylink, which includes the pause modes. In doing this cleanup, several issues were identified with the original xpcs implementation: 1) it masks the link partner advertisement with its own advertisement so userspace can't see what the full link partner advertisement was. 2) it was always setting pause modes irrespective of the advertisements on either end of the link. 3) it was reading the STAT1 registers multiple times. Reading STAT1 has the side effect of unlatching the link-down status, so multiple reads should be avoided. This patch series addresses the first two first by addressing the issues, and then by moving over to the new helpers. The third issue is solved by restructuring the xpcs code. ==================== Link: https://lore.kernel.org/r/ZGyR/jDyYTYzRklg@shell.armlinux.org.uk 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.
