Something like: case SCAN_SEND_PROBE: next_delay = IEEE80211_PASSIVE_CHANNEL_TIME; local->scan_state = SCAN_SET_CHANNEL; if (local->scan_channel->flags & (IEEE80211_CHAN_PASSIVE_SCAN | IEEE80211_CHAN_CSA_DISABLED)) break; ieee80211_send_probe_req(sdata, NULL, local->scan_ssid, local->scan_ssid_len); next_delay = IEEE80211_CHANNEL_TIME; break; But am not sure what constraints are imposed on the station on reception of a CSA.
