| Initialize IP4 forwarding with GTPU tunnel in 3-node circular topology
| | [Documentation]
| | ... | Set UP state on VPP interfaces in path on nodes in 3-node circular
| | ... | topology. Create GTPU tunnel on both DUT nodes, setup IPv4 adresses
| | ... | with /30 prefix on DUT1-DUT2 link, and set routing on both DUT nodes
| | ... | with prefix /24 and next hop of neighbour DUT interface. Gtpu offload
| | ... | rx will be enabled on both DUT nodes if offload is set to true.
