+| | ... | interfaces and interconnecting NF.
+| |
+| | ... | *Arguments:*
+| | ... | - nf_chains - Number of chains of NFs. Type: integer
+| | ... | - nf_nodes - Number of NFs nodes per chain. Type: integer
+| | ... | - jumbo - Jumbo frames are used (True) or are not used (False)
+| | ... | in the test. Type: boolean
+| | ... | - perf_qemu_qsz - Virtio Queue Size. Type: integer
+| | ... | - use_tuned_cfs - Set True if CFS RR should be used for Qemu SMP.
+| | ... | Type: boolean
+| | ... | - auto_scale - Whether to use same amount of RXQs for memif interface
+| | ... | in containers as vswitch, otherwise use single RXQ. Type: boolean
+| | ... | - vnf - Network function as a payload. Type: string
+| | ... | - pinning - Whether to pin QEMU VMs to specific cores
+| |
