| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with multiple\

| ... | and send to another DUT, where packets are decrypted and sent back to TG
| ... | *[Ver] TG verification:* TG finds throughput NDR (Non Drop Rate)\
| ... | with zero packet loss tolerance, then measures loss at this load\
| ... | while additional chain is configured.\
| ... | Test packets are generated by TG on
| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
| ... | (flow-group per direction, number of flows per flow-group equals to
| ... | number of IPSec tunnels) with all packets
| ... | containing Ethernet header, IPv4 header with IP protocol=61 and
| ... | static payload. MAC addresses are matching MAC addresses of the TG
| ... | node interfaces. Incrementing of IP.dst (IPv4 destination address) field
| ... | is applied to both streams.
