Hello, I see mac80211 send this null frame using ieee8011_send_null_response() I am not sure I track this call correctly, but seems: we queue this frame ( invoke_tx_handlers() != 0 ) instead of sending directly via __ieee80211_tx(...). Did I track this call correctly? If yes why we queue this NULL frame?
