          When you add -o you will see it adds TCP packet timer information just as the manual states eg:



          timer:(<timer_name>,<expire_time>,<retrans>)
          timer:(keepalive,30sec,0)

          • @Tim retrans = number of times the packet was re sent due to no acknowledgement packet before the expiration time.
