参考上一篇文章，这里做回顾以及整理：
使用vmware虚拟机（16.04）+dpdk（dpdk-19.08.2.tar）进行测试
增加处理器，增加内存（方便设置多队列网卡，设置大内存页）
修改配置文件后要重启网络服务的，才能生效：sudo service networking restart
一定要在虚拟机关机状态下修改，修改后启动查看
启动后查看多队列网卡（这里网卡没有改为传统的eth命名，重启后网卡的命名会变化，由ens33变成的ens160）：
重新修改一下，使多个网卡都生效：
修改后多网卡：（参考第二步，重新修改/etc/network/interfaces文件）
多队列网卡：
default_hugepages=1G hugepagesz=2M hugepages=1024 isolcpus=0-2
如果报错缺少numa.h 需要安装libnuma-dev
这里我用的39，生成64为的linux上的dpdk，生成一个x86_64-native-linux-gcc目录。
# export RTE_SDK=/home/hlp/dpdk/dpdk-stable-19.08.2
# export RTE_TARGET=x86_64-native-linux-gcc
会失败，关闭要绑定的网卡，重新进行绑定： 例如这里我关闭了ens160多队列网卡： sudo ifconfig ens160 down
会有对应的网卡提示，输入要绑定的网卡的前面的id就好，这里我已经绑定过：
一定要关闭网卡后，执行49的网卡绑定动作，可以重新执行49查看执行成功。
