actually this sounds like a design mistake. If macvlan requires the network 
interface in promiscuous mode, then it should do that internally.

Inside the kernel the promiscuous mode is actually reference counted. This can 
for example be utilized from packet(7) sockets. That way you do not 
accidentally leave a device in promiscuous mode if all users are gone.

So why not fix macvlan to put the parent into promiscuous mode.

Marcel
