The level can be 1-3. The Ext element is added behind the ADDBA request inside the action frame. The responder will then reply with the same level or a lower one if the requested one is not supported. This patch only handles the negotiation part as the ADDBA frames get passed to the ATH11k firmware, which does the rest of the magic for us aswell as generating the requests.
