Maxime Chevallier says: ==================== net: phy: Add 2.5G/5GBASET PHYs support The 802.3bz standard defines 2 modes based on the NBASET alliance work that allow to use 2.5Gbps and 5Gbps speeds on Cat 5e, 6 and 7 cables. This series adds the necessary infrastructure to handle these modes with C45 PHYs. This series was originally part of a bigger one, that has seen 2 iterations [1] [2] that added support for these modes on Marvell Alaska PHYs. Following some discussions with Heiner and Andrew [3], we decided to split-out the generic parts so that we can work together on the following steps to get these mode fully working with Aquantia and Marvell PHYS. The first 3 patches are reworking some of the internal network phy infrastructure to handle the new modes in a more generic way. The 4th patch adds all the C45 register definition and accesses that follows the 802.3bz standard to support 2.5GBASET and 5GBASET.

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.
