From: Simon Wunderlich <[email protected]> When Userspace is capable of handling DFS, it can inform the kernel about that by sending the NL80211_ATTR_HANDLE_DFS attribute when joining an IBSS. DFS channels will then be unlocked.
Note that this flag is only added for debugging purposes and therefore hidden from the user by prefixing with __ and not documenting it.
