[Bug] ovs-dpdk无法接管网卡

[alin-code]

Description

使用kube-ovn:v1.12.18-dpdk的镜像拉起的ovs-dpdk pod，使用dpdk-devbind后无法接管网卡，ovs中有报错

宿主机操作系统是centos7.8，OVS以及dpdk的编译是Ubuntu22.04（使用官方提供的Dockerfile），这是否会造成影响。

已尝试在宿主机安装ovs2.16和dpdk20.11可以接管网卡

Who will benefit from this feature?

经过进一步的测试，发现首先/dev/uio0在pod中是没有的，需要额外挂载这个目录，调整后，ovs-vswtichd的日志里有如下报错：

而已经经过了dpdk-devbind的调整，这里应该是igb_uio才对

[alin-code]

E810的网卡需要挂载两个宿主机的目录，可以成功接管，目前的ovs-dpdk并非开箱即用。我这里的用法是使用igb_uio的driver，还必须关闭iommu才能使用

一些额外的挂载：
volumeMounts:

• mountPath: /lib/firmware/updates/intel/ice/ddp
  name: host-ice
• mountPath: /dev
  name: host-dev

volumes:

• hostPath:
  path: /lib/firmware/updates/intel/ice/ddp
  type: ""
  name: host-ice
• hostPath:
  path: /dev
  type: ""
  name: host-dev
