Introduce the ICE_AQC_PORT_OPT_MAX_LANE_40G constant and update the code to process this new option in both the devlink and the Admin Queue Command GET PORT OPTION (opcode 0x06EA) message, similar to existing constants like ICE_AQC_PORT_OPT_MAX_LANE_50G, ICE_AQC_PORT_OPT_MAX_LANE_100G, and so on. This feature allows the driver to correctly report configuration options for 2x40G on E823 and other cards in the future via devlink. Example command: devlink port split pci/0000:01:00.0/0 count 2 Example dmesg: ice 0000:01:00.0: Available port split options and max port speeds (Gbps): ice 0000:01:00.0: Status Split Quad 0 Quad 1 ice 0000:01:00.0: count L0 L1 L2 L3 L4 L5 L6 L7 ice 0000:01:00.0: 2 40 - - - 40 - - - ice 0000:01:00.0: 2 50 - 50 - - - - - ice 0000:01:00.0: 4 25 25 25 25 - - - - ice 0000:01:00.0: 4 25 25 - - 25 25 - - ice 0000:01:00.0: Active 8 10 10 10 10 10 10 10 10 ice 0000:01:00.0: 1 100 - - - - - - - Signed-off-by: Aleksandr Loktionov <aleksandr.loktionov@intel.com> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Reviewed-by: Paul Menzel <pmenzel@molgen.mpg.de> Tested-by: Rinitha S <sx.rinitha@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.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.
