Later on, this could go completely unnoticed since it is returning `nil` here and `nil` a few lines later.
Maybe just log it for now?

Or if you truly don't care about the result, just get rid of the `if` statement entirely and just call `vbm` without assigning its return value to anything... like this:

```go
if n.DHCP {
  vbm(...)
}
```
