Most wifi chipsets and APs will not let you source L2 packets with a MAC address other than the one associated with your station (which means that forwarding packets through OVS from other source MACs will not work). > Also, is it maybe possible to use only one physical wifi NIC and then > configure multiple virtual interfaces on it? > There's no facility in the wifi standards (at least through N) for virtual interfaces associated with a single station address at L2. -- Nick
