There were no secrets in that dump, but it did reveal a major clue.
A response from your system for your AP was:
mode 2, state 0, is_beacon 0, is_probe_resp 1, length 147
For the number of beacons to be updated, the state has to be 2 or 3. My system
has scan_ssid=1 in the wpa_supplicant configuration file. When the scan
finishes, then a value of 2 is set into the mode variable.
The attached updated patch should set the correct mode even if scanning is not
enabled.
