Not sure I"m understand what you're saying here, the CAC timer handled
in the hostap, kernel doesn't know anything about it. The
WIPHY_FLAG_DFS_CAC_IN_PROGRESS exactly says that DFS master (hostapd)
performs a channel availability check, which also indicates that the
CAC timer is running (if this what you mean).
