| ... | *[Ver] TG verification:* In MaxReceivedRate test TG sends traffic
| ... | at line rate and reports total received/sent packets over trial period.
| ... | 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

| ... | node interfaces. Incrementing of IP.dst (IPv4 destination address) field
| ... | is applied to both streams.
| ... | *[Ref] Applicable standard specifications:* RFC4303 and RFC2544.
