So this is not true that we do not support DFS channels in WW mode. David, sorry I should have clarified, this is not for ath9k. This is for other drivers which do not have custom regulatory domains nor do they have any regulatory hint obtainable from their EEPROM. For those cards that do not have anything like this we make them use the world regulatory domain by default. > 2) Today, I do not believe ath9k code supports DFS detection. If that is what you mean. Therefore STA mode will not support DFS detection. However, STA does support DFS channels. DFS channel support vs DFS detection support is two different things. DFS channel support as a slave device, only has to do passive scanning. > > Let me know if that answers your questions. It does, but would like your advice / review on the idea of enabling DFS channels as passive scan, no-ibss (or any radiation enabled) for cards that use the static default world regulatory domain in the kernel. This would not in any way affect ath9k, ath6kl, or any of our cards, but just help other cards that do not have anything implemented. Luis
