However, this is wrong since certain channel definition are possbile where primary channel may not be a DFS channel but, secondary channel is a DFS channel. For example - channel 36 with 160 MHz bandwidth. In such cases, the flag will not be set which is wrong. Fix this issue by using cfg80211_chandef_dfs_usable() function from cfg80211 which return trues if at least one channel is in usable state. While at it, modify the CAC running debug log message to print the CAC time as well in milli-seconds.
