DPDK-Day0：dpdk编译

1.参考安装：

ubuntu虚拟机22.04.5 内存4G

参考官方链接：

DPDK

执行编译命令报错：

 ninja -C build

FAILED: kernel/linux/igb_uio/igb_uio.ko 

FAILED: kernel/linux/kni/rte_kni.ko 

......
ninja: build stopped: subcommand failed.

解决办法：

打开 /dpdk19.11/config/common_base 文件中CONFIG_RTE_EAL_IGB_UIO=n

# global maximum usable amount of VA, in megabytes
...
CONFIG_RTE_EAL_IGB_UIO=y

应该是内核版本与dpdk版本不适配，试了好几个dpdk版本，最终用20.11编译通过了.

2.版本信息如下
