46.3. lwip_iperf
46.3.1. 概述
本示例通过iperf (https://iperf.fr/iperf-download.php) 测试TCP/UDP吞吐性能，共有如下四种模式：
MCU用作TCP服务端 / PC用作TCP客户端
MCU用作TCP客户端 / PC用作TCP服务端
MCU用作UDP服务端 / PC用作UDP客户端
MCU用作UDP客户端 / PC用作UDP服务端
46.3.2. 硬件设置
使用USB Type-C线缆连接PC USB端口和PWR DEBUG端口
使用以太网线缆连接PC以太网端口和开发板以太网端口
46.3.3. 工程配置
以太网端口配置：参考 : 以太网通用工程设置
以太网DHCP配置
lwIP sample: 在`CMakeLists.txt`中，支持如下配置:
sdk_compile_definitions(-DLWIP_DHCP=0): 禁用DHCP功能
sdk_compile_definitions(-DLWIP_DHCP=1): 启用DHCP功能
sdk_compile_definitions(-DENABLE_TSW_RECEIVE_INTERRUPT=0): 禁用TSW CPU端口接收中断
sdk_compile_definitions(-DENABLE_TSW_RECEIVE_INTERRUPT=1): 启用TSW CPU端口接收中断
