Looks like you're right, there doesn't seem to be a way. I always thought this was possible. I think you should raise this point on the mailing list again. I've proposed doing this through nl80211 to allow extensibility of the meta information (frame rate, ....) for an injected frame instead of conjuring up yet another meta information framework that transports frame across netdevs, but Michael strongly opposes the idea of transporting frames via anything but a netdev. I could post some code for nl80211 inject that doesn't control any meta information yet but at least has the capability of carrying it over to the stack. johannes
