基于测试USER DMA 压力测试需求。
2. Iperf3
2.1 基本框架介绍
Iperf3 发送数据包 TCP/UDP 包
1. 查看网卡配置信息
2. 此处因共用一张板卡，所以使用网络命令空间将网卡swift1f0 与swift1f1 分隔
swift1f0： 11.1.1.73/24
swift1f1： 11.1.1.77/24 网络命令空间：netABC
# 具体配置信息查看 # https://blog.csdn.net/weixin_57632548/article/details/144208553
3. 启动Iperf3 Server 端
4. 启动Iperf3 TCP/UDP Client 端2.2 Iperf3 发送TCP包

3. 启动Iperf3 Server 端
# iperf3 -B <网口 IP> -p <端口号> -i 1 -s
4. 启动Iperf3 UDP Client 端
# iperf3 -c <Server IP> -p <Server Port> -t <Client 发送请求时间>
