The Syn-Recv status means the +TCP stack receives a SYN and replies SYN+ACK. Now the TCP stack is +waiting for an ACK. Generally, the TCP stack doesn't need to send ACK +in the Syn-Recv status. But in several scenarios, the TCP stack need +to send an ACK. E.g., the TCP stack receives the same SYN packet +repeately, the received packet does not pass the PAWS check, or the +received packet sequence number is out of window.
