Add ability to change speed through ethtool -s <interface> speed <speed in Mb> Driver advertises all link modes that support requested speed. Autoneg must be set off e.g.: ethtool -s <interface> autoneg off speed <speed in Mb>. Add helper function that translate speed in Mb to enum i40e_aq_link_speed and compare it to supported speeds from given ethtool_link_ksettings. Add in i40e_set_link_ksettings hold for requested speed and set copy_ks.base.speed to safe_ks.base.speed to be sure that user is not changing unsupported setting. In i40e_speed_to_link_speed compare requested speed with supported speeds. Set speed to requested speed.

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.
