There is no such thing as default speed. Speed is either:
1) Negotiated with the link partner, picking the highest speed link
modes both partners support
2) Forced to a specific speed, based on one of the link modes the
interfaces supports.
Since you don't have link modes, you are abusing the API. You should
choose a different API which actually fits what you are doing,
configuring a leaky bucket shaper.
