	Thanks for the answer. 

	The ATH9K_HW_CAP_DFS is set in hw.c only  if the function
ath9k_hw_dfs_tested return true.

	In the ath9k/init.c, the function ath9k_set_hw_capab do not set any
flags in hw->flags relevant to DFS.

	I'm looking for a similar line
	if (sc->sc_ah->caps.hw_caps & ATH9K_HW_CAP_DFS)
      	hw->flags |= IEEE80211_HW_xxxx;
	
	But I don't found. 

	I'm looking in net/mac80211.h the IEEE80211 flag relevant to DFS (to
add the test in ath9k init), but I don't found it.

	It seem the mac80211 do not know the hardware capability to detect
radar.

	Cedric.
