+| ... | *[Cfg] DUT configuration:* DUT1 is configured with multiple IPsec\
+| ... | tunnels between it and TG. DUT gets IPv4 traffic from TG, encrypts it\
+| ... | and sends 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 tunnels are configured.\
+| ... | Test packets are generated by TG on
+| ... | links to DUTs. TG traffic profile contains one 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 the stream.
+| ... | *[Ref] Applicable standard specifications:* RFC4303 and RFC2544.
