commit 65b709586e222fa6ffd4166ac7fdb5d5dad113ee upstream. The get_config callback can be used by the device to fill the config structure. The callback will be invoked in vdpasim_get_config() before copying bytes into caller buffer. Move vDPA-net config updates from vdpasim_set_features() in the new vdpasim_net_get_config() callback. This is safe since in vdpa_get_config() we already check that .set_features() callback is called before .get_config().

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.
