TSHttpTxnServerPacketTosSet - change packet TOS for the server side connection

       2025, dev@trafficserver.apache.org

9.2                                               May 22, 2025                  TSHTTPTXNSERVERPACKETTOSSET(3ts)

NOTE:
          The  change  takes effect immediately. If no OS connection has been made, then this sets the mark that
          will be used. If an OS connection is established

          TOS is deprecated and replaced by DSCP. This is still used to set DSCP, however the first  2  bits  of
          this value will be ignored as they now belong to the ECN field.
