USER1：初始化端口 0 EAL：错误 - 退出代码：1 原因：无法设置 TX 队列；端口 = 0，错误 = 无效参数 (fastcapa)

如何解决USER1：初始化端口 0 EAL：错误 - 退出代码：1 原因：无法设置 TX 队列；端口 = 0，错误 = 无效参数 (fastcapa)

我正在尝试在安装并构建了 dpdk 和 librdkafka 的 VM（ubuntu20.04）上运行 fastcapa（metron 项目）。 但是当我运行这个命令时，我收到了这个错误： 命令：sudo ./fastca pa -c 0x0f -n 1 --huge-dir /mnt/huge_1GB -- -p 0x00 -t pcap -c /etc/project/metr on/metron-sensors/fastcapa/conf/fastcapa.conf 错误：

EAL: Error - exiting with code: 1

谁能帮忙解决这个问题。 谢谢。

解决方法

根据 metron github 链接，建议的示例命令是

fastcapa -c 0x03 --huge-dir /mnt/huge_1GB -- -p 0x01 -t pcap -c /etc/fastcapa.conf

其中端口掩码设置为 -p 0x01。在您当前运行的应用程序中，端口 maks 设置为零。
