[Qemu-devel] [PATCH v6 0/2] vhost-user multi queue support |

Vhost-user will implement the multi queue support in a similar way
to what vhost already has - a separate thread for each queue.
To enable the multi queue functionality - a new command line parameter
"queues" is introduced for the vhost-user netdev.
Use new message VHOST_USER_SET_VRING_FLAG to enable and disable an
actual virt queue, which is similar to attach/detach queue for tap device.
virtio driver on guest doesn't have to use max virt queue pair, it could
enable any number of virt queue ranging from 1 to max virt queue pair.
It requires that VHOST_USER_F_PROTOCOL_FEATURES is present.
Any comment is welcome for the patch set.
It has dependency on a few other patch(set):
"vhost-user: protocol updates" series
proposed earlier by Michael S. Tsirkin
RESET_OWNER change is based on commit:
