revert back to AOKP codebase
tether: Link to legacy wifi for tiap_drv module based wlan #5

remember to add this in system.prop :
  wifi.hotspot.ti = 1
  wifi.ap.interface = tiap0

and in the frameworks overlay :
  <!-- whether Softap rely on a different interface (beware these flags can be badly understood) -->
  <bool name="config_wifi_ap_use_single_interface">true</bool>

  <!-- Dont reload the firmware via the framework, let wifi legacy and tiap_loader do that -->
  <bool name="config_wifi_ap_firmware_reload">false</bool>
