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.
