Trying to use the tuning plugin through multus, I got the following stacktrace:
```

By bruteforce matching this to a version in the CNI repo, I figured this is from the 0.7 branch, that 's over 2 years old.
Posting my above problem, the sandbox error, here or upstream seems futile, until CDK incorporates the latest CNI binaries. As such the title of the "bug" is chosen to represent the shear fact that the current binaries are over 2y old.
