Suggest to add a summary of what we learned during review. Let me try. The two new types need to parsed the modern way with -netdev, because <explanation goes here>. The previous commit paved the way for parsing the modern way, but omitted one detail: how to pick modern vs. traditional, in netdev_is_modern(). We want to pick based on the value of parameter "type". But how to extract it from the option argument? Parsing the option argument, either the modern or the traditional way, extracts it for us, but only if parsing succeeds. If parsing fails, there is no good option. No matter which parser we pick, it'll be the wrong one for some arguments, and the error reporting will be confusing. Fortunately, the traditional parser accepts *anything* when called in a certain way. This maximizes our chance to extract the value of "type", and in turn minimizes the risk of confusing error reporting. How do you like it?
