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
