Virtio-net driver control queue implementation is not safe when used with VDUSE. If the VDUSE application does not reply to control queue messages, it currently ends up hanging the kernel thread sending this command. Some work is on-going to make the control queue implementation robust with VDUSE. Until it is completed, let's fail features check if control-queue feature is requested.

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.
