| Documentation | *DMM vs epoll test suite.*
| ...
| ... | Test suite uses 3-node topology TG - DUT1 - DUT2 - TG with single link
| ... | between nodes. From this topology only DUT1 and DUT2 nodes are used.
| ... | here we test the 1. test the vs_epool and vc_epoll

*** Variables ***
| ${ip4_net1_1}= | 172.28.128.3
| ${ip4_net2_1}= | 172.28.128.4
| ${ip4_prefix}= | 24

*** Test Cases ***
| TC01: DMM base vs epoll test case
| | Given DMM Basic Test Setup
| | When Exec the base vs epoll test | ${dut1_node} | ${dut2_node}
| | ... | ${dut1_to_dut2_if_name} | ${dut2_to_dut1_if_name}
| | ... | ${ip4_net1_1} | ${ip4_net2_1}
| | Echo DMM logs | ${dut2_node}
| | ${no_packet_loss} = | Get the test result | ${dut2_node}
| | Then Should Not Be Equal As Integers | ${no_packet_loss} | 0

| TC02: DMM LWIP integration test case
| | Given DMM Basic Test Setup
| | When Exec the base lwip test | ${dut1_node} | ${dut2_node}
| | ... | ${dut1_to_dut2_if_name} | ${dut2_to_dut1_if_name}
| | ... | ${ip4_net1_1} | ${ip4_net2_1}
| | Echo running log | ${dut1_node} | ${dut2_node}
| | Echo dpdk log | ${dut1_node} | ${dut2_node}
| | ${no_packet_loss_lwip} = | Get lwip test result | ${dut2_node}
