+| Set up SRIOV 2-node performance topology with DUT's NIC model
+| | [Documentation]
+| | ... | Suite preparation phase that sets default startup configuration of
+| | ... | VPP on all DUTs. Updates interfaces on all nodes and sets global
+| | ... | variables used in test cases based on interface model provided as an
+| | ... | argument. Initializes traffic generator.
+| | ... | It configures PCI device with VFs on all DUTs.
+| | ...
+| | ... | *Arguments:*
+| | ... | - topology_type - Topology type. Type: string
+| | ... | - nic_model - Interface model. Type: string
+| | ... | - vf_driver - Virtual function driver. Type: string
