So that is half the battle to get the broadcast system working with mac80211 out of the box without patches. However, if I inject a captured packet - with a PRISM header prepended - down the Monitor mode interface using pcap_inject(), I see it appear on the libpcap captured output okay, but it does not go out on the air AFAICT. Is this in fact the correct way to try to inject a packet with fine control over its encryption and rate? If so is it expected to currently work on iwlwifi 0.0.8 or rt2x00 (rt73usb) from CVS 2008-02-14? -Andy
