One question.
Mostly seems fine though I'm not a network expert.

It seems like we are always setting this now.
Is there a behavior change here?

No behavior change here. Bridge (0) is the traditional mode where slaves can cross-talk among
themselves apart from talking through the master device.

It will get optimized out by the compiler anyway, but it seems like these could simly be driverModeOpt = "ipvlan_mode", since the variable never appears be reassigned anywhere. Honestly, it could probably be a const, but that's nitpicky. Still, the concatenation should just be a string literal, otherwise a reader may spend time looking through the codebase to see if it ever changes.

There are many references of ipvlanType all around this driver, all of them are redundant. Considering the similarity between macvlan and ipvlan, maybe the original author of the code intentionally leave an extra level of indirection to make code refactoring (identifier renaming) easier and more confident. I tried to keep the original style when introducing my changes.

LGTM in general. A small nitpick, but not worth blocking on. |
