-| Configure MTU on TG based on MTU on DUT
-| | [Documentation] | Type of the tg_node must be TG and dut_node must be DUT
-| | [Arguments] | ${tg_node} | ${dut_node}
-| | Append Nodes | ${tg_node} | ${dut_node}
-| | Compute Path
-| | ${tg_port} | ${tg_node}= | First Interface
-| | ${dut_port} | ${dut_node}= | Last Interface
-| | # get physical layer MTU (max. size of Ethernet frame)
-| | ${mtu}= | Get Interface MTU | ${dut_node} | ${dut_port}
-| | # Ethernet MTU is physical layer MTU minus size of Ethernet header and FCS
-| | ${eth_mtu}= | Evaluate | ${mtu} - 14 - 4
-| | Set Interface Ethernet MTU | ${tg_node} | ${tg_port} | ${eth_mtu}
