      P2P: Improve robustness against lost ctrl::ack · 2c5b17df
      Jouni Malinen authored
      P2P includes two use cases where one of the devices is going to start a
      group and likely change channels immediately after processing a frame.
      This operation may be fast enough to make the device leave the current
      channel before the peer has completed layer 2 retransmission of the
      frame in case the ctrl::ack frame was lost. This can result in the peer
      not getting TX status success notification.
      
      For GO Negotiation Confirm frame, p2p_go_neg_conf_cb() has a workaround
      that ignores the TX status failure and will continue with the group
      formation with the assumption that the peer actually received the frame
      even though we did not receive ctrl::ack. For Invitation Response frame
      to re-invoke a persistent group, no such workaround is used in
      p2p_invitation_resp_cb(). Consequently, TX status failure due to lost
      ctrl::ack frame results in one of the peers not starting the group.
      
      Increase the likelihood of layer 2 retransmission getting acknowledged
      and ctrl::ack being received by waiting a short duration after having
      processed the GO Negotiation Confirm and Invitation Response frames for
      the re-invocation case. For the former, use 20 ms wait since this case
      has been worked around in deployed devices. For the latter, use 50 ms
      wait to get even higher likelihood of getting ctrl::ack through since
      deployed devices (and the current wpa_supplicant implementation) do not
      have a workaround to ignore TX status failure.
      
      20 ms is long enough to include at least couple of retries and that
      should increase likelihood of getting ctrl::ack through quite a bit. The
      longer 50 ms wait is likely to include full set of layer 2 retries.
