wondering what this opening was called

I guess it's a line of the French Two Knights, but ...Nc6 looks unusual.
...Nc6 always looks unusual in the French, since Black usually wants to play ...c5 at some point. But it's fashionable recently to try it in several lines, perhaps here as well... But I think 1.e4 e6 2.Nf3 d6 3.Nc3 Nf6 is better.
