openEuler-22.03-LTS-SP1中自带的i40e网卡驱动，无法虚拟网卡

**【标题描述】能够简要描述问题：说明什么场景下，做了什么操作，出现什么问题（尽量使用正向表达方式）**

**一、缺陷信息**
openEuler-22.03-LTS-SP1中自带的i40e网卡驱动，无法虚拟网卡

**内核信息：**
5.10.0-136.65.0.145.oe2203sp1.x

**缺陷归属组件：**
kernel

**缺陷归属的版本：**
5.10.0-136.65.0.145.oe2203sp1.x

**缺陷简述：**
使用X722型号的网卡，默认使用i40e驱动，使用下面命令虚拟化网卡时，虚拟化网卡的结果与预期不符

- 虚拟机场景请提供虚拟机的XML文件或配置信息
软件信息
- OS版本及分支信息
- 内核信息
- 发现问题的组件版本信息
网络信息
- 如果有特殊组网，请提供网络拓扑信息

**【问题复现步骤】**，请描述具体的操作步骤
1、在X722型号的网卡中，安装openEuler-22.03-LTS-SP1的系统
2、确认i40e驱动已加载
3、echo 5 > /sys/class/net/xxx/device/sriov_numvfs
其中，xxx是加载了i40e驱动的网卡名
4、ip a检查虚拟网卡结果

**【实际结果】**，请描述出问题的结果和影响
预期应该虚拟出五个网卡，但实际只有一个
