Bug Description
I tried to setup a libvirt + kvm host connected to the main network using macvtap with the wlan0 device, however the virtual host was not able to get any IP address using DHCP.
If I set the IP address manually, it still doesn't work, however with tcpdump I'm able to see from the physical host some traffic comming from a ping running inside the virtual host to the external network.
macvtap works without problems on a cable device. Also, virtualbox is able to setup a bridge like interface over wifi, so seems like is not a limitation on the wifi driver.
If you tell me about the debugging information you would need to fix this issue, I will be happy to provide it attached to this bug report.

I don't believe macvlan is supported on wifi devices at all. Whenever I try, not only does the macvtap device not work, but my host's wifi connection needs to be reset.
I can mark this as affecting the kernel, but this is not a qemu bug and I suspect that in the kernel it is simply not supported, just like bridging the wifi device.
