Probably worth defining these in a common place.

Is there a translation layer between these and networkingPrivate? If not, we
should use the ONC constants directly.

[mef, 2013/08/21 17:25:34]

I'd love to use ONC constants, but they seem to be ChromeOS-specific. Should I
move them somewhere?

Done.

One advantage to sticking with strings is not having to maintain a bunch of
functions like these. I can almost guarantee you will also want the inverse of
these soon if you use enums...

[mef, 2013/08/21 17:25:34]

Good point, will follow your advise.

[mef, 2013/10/08 21:46:25]

Done.

nit: } on separate line here and above

This is result of automatic clang-format, not sure if it fits the guidelines.
