+        tx_offloads: Set the hexadecimal bitmask of TX queue offloads.
+        eth_link_speed: Set a forced link speed to the ethernet port. E.g. 1000 for 1Gbps.
+        disable_link_check: Disable check on link status when starting/stopping ports.
+        disable_device_start: Do not automatically start all ports. This allows testing
+                              configuration of rx and tx queues before device is started
+                              for the first time.
+        no_lsc_interrupt: Disable LSC interrupts for all ports, even those supporting it.
+        no_rmv_interrupt: Disable RMV interrupts for all ports, even those supporting it.
+        bitrate_stats: Set the logical core N to perform bitrate calculation.
+        latencystats: Set the logical core N to perform latency and jitter calculations.
+        print_events: Enable printing the occurrence of the designated events.
+                      Using :attr:`TestPmdEvent.ALL` will enable all of them.
+        mask_events: Disable printing the occurrence of the designated events.
+                     Using :attr:`TestPmdEvent.ALL` will disable all of them.
+        flow_isolate_all: Providing this parameter requests flow API isolated mode on all ports at
+                          initialization time. It ensures all traffic is received through the
+                          configured flow rules only (see flow command). Ports that do not support
+                          this mode are automatically discarded.
+        disable_flow_flush: Disable port flow flush when stopping port.
+                            This allows testing keep flow rules or shared flow objects across
+                            restart.
+        hot_plug: Enable device event monitor mechanism for hotplug.
+        vxlan_gpe_port: Set the UDP port number of tunnel VXLAN-GPE to N.
+        geneve_parsed_port: Set the UDP port number that is used for parsing the GENEVE protocol
+                            to N. HW may be configured with another tunnel Geneve port.
+        lock_all_memory: Enable/disable locking all memory. Disabled by default.
+        mempool_allocation_mode: Set mempool allocation mode.
+        record_core_cycles: Enable measurement of CPU cycles per packet.
+        record_burst_status: Enable display of RX and TX burst stats.
