+            false implies a software-based approach.
+        data_path (str): Specifies the data path technology used. Current options include:
+            - 'AF_PACKET'
+            - 'AF_XDP_ZC'
+            Future expansions may include other data paths like 'DPDK'.

+        launch_time_control (bool): Enables or disables launch time control for packets.
