# `gateway_ip_addrs_step`: step for generating router gateway sequences. default is 0.0.0.1
# `udp_src_port`: the source port for sending UDP traffic, default is picked by TRex (53)
# `udp_dst_port`: the destination port for sending UDP traffic, default is picked by TRex (53)
+ # `mac_addrs_left` & `mac_addrs_right`: Lists of MAC addresses corresponding to the number of chains
+ # specified for `service_chain_count`.
+ # - If both lists are empty the far end MAC of the traffic generator will be used for left and right
+ # - The MAC addresses will only be used when `service_chain` is EXT and `no_arp` is true.
+ # - The length of each list must match the number of chains being used.
+ # - The index of each list must correspond to the chain index to ensure proper pairing.
+ # - Below is an example of using two chains:
+ # - mac_addrs_left: ['00:00:00:00:01:00', '00:00:00:00:02:00']
+ # - mac_addrs_right: ['00:00:00:00:01:01', '00:00:00:00:02:01']
