I'm doing some tests in 802.11a with ath9k driver and I found a strange behavior. With iw phy0 info, I check the regulation rules. I can see some channels needs radar detection. For test I set an AP on this channel and I can see the beacon with wireshark. But ATH9K doesn't support radar detection, so these channels should be disabled. I think the problem is on MAC80211 layer. In /net/wireless/reg.c the function map_regdom_flags set the flags IEEE80211_CHAN_RADAR if the regulatory domain set NL80211_RRF_DFS. But ATH9K doesn't support the radar detection, and I don't found in MAC80211 a test on this capability. I only found a capabilities in ATH9K (ATH9K_HW_CAP_DFS), but this flag is set and not used. I don't know how fix this issue. For the moment I disable the channel when the NL80211_RRF_DFS is set (in map_regdom_flags).
