qemu:virtio-net: Add promiscuous and all-multicast mode bits (Alex Williamson)
Add a new RX_MODE control virtqueue class with commands PROMISC and ALLMULTI and usage documented in virtio-net.h allowing the guest to manipulate packet receiving options. We don't export a feature for this until we also add the MAC filter table. Note, for compatibility with older guest drivers we need to default to promiscuous.
