Alexander Duyck says: ==================== net: phy: Add support for fbnic PHY w/ 25G, 50G, and 100G support To transition the fbnic driver to using the XPCS driver we need to address the fact that we need a representation for the FW managed PMD that is actually a SerDes PHY to handle link bouncing during link training. This patch set introduces the necessary bits to the XPCS driver code to enable it to read 25G, 50G, and 100G speeds from the PCS ctrl1 register, and adds support for the approriate interfaces. The rest of this patch set enables the changes to fbnic to make use of these interfaces and expose a PMD that can provide a necessary link delay to avoid link flapping in the event that a cable is disconnected and reconnected, and to correctly expose the count for the link down events. With this we have the basic groundwork laid as with this all the bits and pieces are in place in terms of reading the configuration. The general plan for follow-on patch sets is to start looking at enabling changing the configuration in environments where that is supported. ==================== Link: https://patch.msgid.link/176374310349.959489.838154632023183753.stgit@ahduyck-xeon-server.home.arpa Signed-off-by: Paolo Abeni <pabeni@redhat.com>
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.
