Replaying traffic onto a wireless network is unfortunately a lot
harder then it should be.  From what I can tell, it seems to be
NIC/driver dependent and hence I've pretty much punted on this for
tcpreplay.  Many combinations appear not possible. What I would
recommend you look at is lorcon or libradiate to actually inject
frames onto 802.11 networks.

Maybe one of these days I'll use lorcon in tcpreplay, but my access to
hardware is limited so testing tends to be a problem.
