This patch adds a network interface backend driver to qemu. It is a pure userspace implemention using the gntdev interface. It uses "qnet" as backend name in xenstore so it doesn't interfere with the netback backend (aka "vnif"). The network backend is hooked into the corrosponding qemu vlan, i.e. vif 0 is hooked into vlan 0. To make the packages actually arrive somewhere you additionally have to link the vlan to the outside world using the usual qemu command line options such as "-net tap,...".
