Hi all, Now that some code has been submitted to ath9k to decode radar frames, I've pushed my local radar decoding code into -HEAD. This now means that (almost) all the relevant information is freely available for those who wish to write a radar pattern classification module for FreeBSD. The only two missing pieces are: * some default values for the radar detection block (ie, RSSI/duration thresholds); * pulse width -> usec duration calculation (which I'll look at committing shortly.) I'll update the ath/hal documentation on the FreeBSD wiki with the capabilities of each of the 11n chips. The current rule to keep in mind is "don't try this for anything less than AR9280 unless you know what you're doing; and you likely don't know what you're doing." I'll document more about this in the Wiki. Finally, I do have working radar classification code for the AR9220/AR9280 and can port over the code needed for it to work for the AR9160. It's just not (yet) able to be open sourced. Please contact me if you're a company (ie, willing to do the regulatory testing needed) and would like to discuss how to leverage that. Thanks, Adrian
