Ido Schimmel says: ==================== mlxsw: Add support for new port types and speeds for Spectrum-2 Shalom says: This patchset adds support for new port types and speeds for Spectrum-2. Patch #1 + #2 removes an unsupported PTYS field and a duplicate link mode entry. Patch #3 queries port's connector type from firmware instead of deriving it from port admin state. Patch #4 renames functions which relate to port type-speed to be Spectrum-1 specific. Patch #5 defines port type-speed operations and applies it for Spectrum-1. Patch #6 + #7 are small renaming and cosmetic changes. Patch #8 adds new port type-speed fields for PTYS register. These new fields extend the existing ones in order to support more types and speeds. Patch #9 adds Spectrum-2 support for port type-speed operations. Patch #10 adds Spectrum-2 new port types and speeds. For Spectrum-2, the user must configure all the types per speed if he / she wants a specific speed to be advertised. For example, if the user wants to advertise 100Gbps 4-lanes speed, the following ethtool bits should be advertised: Supported ethtool bits for 100Gbps 4-lanes: 0x1000000000 100000baseKR4 Full 0x2000000000 100000baseSR4 Full 0x4000000000 100000baseCR4 Full 0x8000000000 100000baseLR4_ER4 Full Command for advertising 100Gbps 4-lanes: ethtool -s enp3s0np1 advertise 0xF000000000 ==================== Signed-off-by: David S.

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.
