Hi, I'll repost this, as it seems emailing lists.ath9k.org doesn't seem to work out. The formats are as follows. Please note that if a pulse terminates during an FFT, the final entry may be truncated. So yes, you may not always get an integer multiple of the relevant frame length. Note that you

2012-11-27 Thread Simon Wunderlich
Adds the spectral scan feature for ath9k. AR92xx and AR93xx chips are supported for now. The spectral scan is triggered within a channel scan from mac80211, results can be gathered via debugfs. Signed-off-by: Simon Wunderlich s...@hrz.tu-chemnitz.de Signed-off-by: Mathias Kretschmer
