Initialize all the ethtool ops that are supported by the driver and add the necessary support for the ethtool callbacks. Also add asynchronous link notification virtchnl support where the device Control Plane sends the link status and link speed as an asynchronous event message. Driver report the link speed on ethtool .idpf_get_link_ksettings query. Introduce soft reset function which is used by some of the ethtool callbacks such as .set_channels, .set_ringparam etc. to change the existing queue configuration. It deletes the existing queues by sending delete queues virtchnl message to the CP and calls the 'vport_stop' flow which disables the queues, vport etc. New set of queues are requested to the CP and reconfigure the queue context by calling the 'vport_open' flow. Soft reset flow also adjusts the number of vectors associated to a vport if .set_channels is called.

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.
