As FCC DFS requirement does not explicitly mention about the validity of the (pre-)CAC when channel is switched, it is safe to assume that the pre-CAC result will not be valid once the CAC completed channel is switched or radar detection is not active on the (CAC completed) channel within a time period which is allowed (10 seconds - channel switch time) as per FCC DFS requirement. Use the new driver event to allow the driver to notify expiry of the CAC result on a channel. Move the DFS state of the channel to 'usable' when processing pre-CAC expired event. This means any future operation on that channel will require a new CAC to be completed. This event is applicable only when DFS is not offloaded to the kernel driver.
