I looked the DFS pattern detector set in ath9k driver and the "comment specifies" it compliant with the ETSI standard in V1.5.1. If I correctly understood the ath9k source code and the ETSI EN 301 893 standard, the table D.3 and D.4 in Annexes D of ETSI standard it uses to fill the ETSI_radar_ref_types_v15 structure. The difference between these tables in EN 301 893 v1.5.1 and EN 301 893 v1.7.1 is only the minimal pulse width (from 0.8 to 0.5). This value is set to 0 in many structure fields. Could you confirm the ETSI ath9k pattern detector is compatible with the ETSI EN 301 893 v1.7.1 standard? If it is right, I will send a patch to precise that in ath9k comment. Thanks for your help.
