| ...
| ... | Test suite uses 3-node topology TG - DUT1 - DUT2 - TG with single link
| ... | between nodes. From this topology only TG and DUT1 nodes are used.
| ... | In VM environment, the DUT2 is not configured since the DUT1 is testing
| ... | with the pcap file that generated with the pcap_gen.py. There is no 
| ... | packet going out to DUT2, udpfwd app is verified on DUT1 only.
| ... | This test case just use the pcap file for the UDP functional test.

| TC01: TLDK IPv4 assemble test case
| | Given Path for 2-node testing is set | ${nodes['TG']} | ${nodes['DUT1']}
| | And Pick out the port used to execute test
