[RFC PATCH 00/24] Control VQ support in vDPA
Hi All:
This series tries to add the support for control virtqueue in vDPA.
Control virtqueue is used by networking device for accepting various
commands from the driver. It's a must to support multiqueue and other
configurations.
When used by vhost-vDPA bus driver for VM, the control virtqueue
should be shadowed via userspace VMM (Qemu) instead of being assigned
directly to Guest. This is
