As the current virtio-mmio only support single irq, so some advanced features such as vhost-net with irqfd are not supported. And the net performance is not the best without vhost-net and irqfd supporting. This patch support virtio-mmio to request multiple irqs like virtio-pci. With this patch and qemu assigning multiple irqs for virtio-mmio device, it's ok to use vhost-net with irqfd on

From: Li Liu <john.liuli at huawei.com> This set of patches try to implemet irqfd support of vhost-net based on virtio-mmio. I had posted a mail to talking about the status of vhost-net on kvm-arm refer to http://www.spinics.net/lists/kvm-arm/msg10804.html. Some dependent patches are listed in the mail too. Basically the vhost-net brings great performance improvements, almost 50%+.

Also do you think you would be able to merge the driver (corresponding v4 patch follows) in the 3.2 merge window that seems to have just opened?
