TCP communication, the remote sent an ACK packet with SACK option, lwIP did
not retransmit, but continued to send data, Later, the remote sent a fast
retransmission request, lwIP did not retransmit the data, but continued to
send data.
The attachment is the network packet capture data.
You can use the "tcp && tcp.port==1081" condition to filter out other packets.
