As multi-queue nics were commonly used for high-end servers, current single queue based tap can not satisfy the requirement of scaling guest network performance as the numbers of vcpus increase. So the following series implements multiple queue support in tun/tap. In order to take advantages of this, a multi-queue capable driver and qemu were also needed. I just rebase the latest version of

multiple queue virtio-net: flow steering through host/guest cooperation Hello all: This is a rough series adds the guest/host cooperation of flow steering support based on Krish Kumar's multiple queue virtio-net driver patch 3/3 (http://lwn.net/Articles/467283/). This idea is simple, the backend pass the rxhash to the guest and guest would tell the backend the hash to queue mapping when
