| Setup 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}
