We used to have a per device feature whitelist to filter out the unsupported virtio features. But this seems unnecessary since: - the main idea behind feature whitelist is to block control vq feature until we finalize the control virtqueue API. But the current vhost-vDPA uAPI is sufficient to support control virtqueue. For device that has hardware control virtqueue, the vDPA device driver can just setup the hardware virtqueue and let userspace to use hardware virtqueue directly. For device that doesn't have a control virtqueue, the vDPA device driver need to use e.g vringh to emulate a software control virtqueue. - we don't do it in virtio-vDPA driver So remove this limitation.

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.
