Don't forget "mac-address", if the device is opened
in OF; and "max-frame-size" please.

Can you find a better name? What is this used for, anyway?

See "max-frame-size", MTU is on a higher level than device
level and as such shouldn't be here; the OF networking layer
can set something like this if it wants.

In bytes?
