Ignoring the absurdity of this design, if a device takes in and exhausts air from the same face, there's no need to track airflow direction.

Yes, it's a silly design IMHO but it exists and was a relatively popular router in it's day. If we can't have "front-to-front" can we get "other" to indicate that it's not a passively cooled device and that the airflow is not unknown (which None would indicate to me).

I'm going to add an option for "mixed," which IMO should cover all such odd corner cases.
