Had tested this patch with following scenarios: VIRTIO_NET_CTRL_RX_MODE 1) ip link eth0 promisc on/off 2) ip link set eth0 allmulticast on/off 3) ip link set eth0 multicast on/off VIRTIO_NET_CTRL_MAC 4) ifconfig eth0 hw ether 52:54:00:12:34:57 5) ping guest after joined guest into multicast group (225.0.0.1 ~ 225.0.0.10) VIRTIO_NET_CTRL_VLAN 6) vconfig add eth0 2; vconfig rem eth0.2
