VF is not allocated after recreating a pod

[hassiweb]

I'm facing a similar issue to #14. The device plugin worked once, but the device plugin has not allocated a VF to a pod due to insufficient rdma/vhca after recreating the pod. Then, I tried to disable and enable SR-IOV and to reload the driver, but it doesn't work.

Here is the log on the device plugin.

Kubernetes version is

Server Version: version.Info{Major:"1", Minor:"17", GitVersion:"v1.17.3", GitCommit:"06ad960bfd03b39c8310aaf92d1e7c12ce618213", GitTreeState:"clean", BuildDate:"2020-02-11T18:07:13Z", GoVersion:"go1.13.6", Compiler:"gc", Platform:"linux/amd64"}

The device plugin would be the latest version. But I don't know why the digest ID is not different from one on Dockerhub and it doesn't start when indicating the same digest ID on Dockerhub in the manifest.
