Hiya, I've brought in the spectral scan code for the ar93xx and later chips. It wasn't that much work. To use it: * add ATH_ENABLE_RADIOTAP_VENDOR_EXT, ATH_DIAGAPI to your kernel config and rebuild. I'd love to have this radiotap vendor data be in by default by tcpdump doesn't decode radiotap vendor data correctly yet and doesn't skip over it :( * compile athspectral (tools/ath/ath); to see it just 'athspectral enable_on_reset 1' * sysctl dev.ath.0.monpass=0xffff (so it passes up all PHY error frames up to the stack via radiotap - spectral scan data and radar reports are PHY errors with a payload); * ifconfig wlanX create wlandev ath0 ssid foo123 up (so it stays up and continuously scans, but hopefully never finds the ssid 'foo123'); * clone github.com/erikarn/ath_radar_stuff, build, and run 'fft_eval ar9280 if wlanX' (where 'wlanX' is the wlan interface); * watch the pretty data -adrian
