Hi, xuyanjie,
Few minor coments:

  should has -> should have:

+        # Generally, testbed should has 4 ports NIC, like,
> +        # 03:00.0 03:00.1 03:00.2 03:00.3
> +        # This test case will
> +        # - physical link is 03:00.0 <-> 03:00.1 and 03:00.2 <-> 03:00.3
> +        # - bind 03:00.0 and 03:00.2 to ipsec-secgw app
> +        # - send test packet from 03:00.3

Should be dts ports.cfg

Should be:
              self.logger.info("Test trs_qat_aes_128_ctr_ipv4_transport")

+        self.logger.info("Test trs_qat_aes_128_ctr_ipv4")

> +        self.logger.debug(ipsec_gw_opt_str)
> +
