Actually I've never thought about it.
My router device is not for public sale, and the device might have been
locked up in recent versions, so I don't think anyone can ever use it
for that specific model.
Come to think of it, I've tried another model before, which is more in
public, I might submit its device tree if it gets ready someday.

Thanks.
