Yes. AP DFS mode has issue when radar detection happened. Patch to fix this issue will
be submitted later.

However, if AP DFS mode without radar detection, it can work. But if VDLL porting is not correct,
command timeout will happen when AP DFS mode is running.

Another way is try to use client mode to connect to external AP running on DFS channel.
