Currently, when auto negotiation is set to off, the user can force a specific speed or both speed and duplex. The user cannot influence the number of lanes that will be forced. Add support for setting speed along with lanes so one would be able to choose how many lanes will be forced. When lanes parameter is passed from user space, choose the link mode that its actual width equals to it. Otherwise, the default link mode will be the one that supports the width of the port.

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.
