Multiqueue support requires additional virtio_net_q objects to be added or removed per the configured number of queue pairs. In addition the RQ tables needs to be modified to match the number of configured receive queues so the packets are dispatched to the right virtqueue according to the hash result. Note: qemu v6.0.0 is broken when the device requests more than two data queues; no net device will be created for the vdpa device. To avoid this, one should specify mq=off to qemu. In this case it will end up with a single queue. Signed-off-by: Eli Cohen <elic@nvidia.com> Link: https://lore.kernel.org/r/20210823052123.14909-7-elic@nvidia.com Signed-off-by: Michael S.

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.
