What about specifying the routing algorithm directly on "soft-iface creation" and deny any further change?

Emails crossed in the post....

1. specify the soft-iface name => create the interface and allocate all the

structure (that are not dependant on the routing algo)

1.1) the interface is in ALGO-WAITING state, any action that tries to enable it is denied and EBUSY (?) is returned.

We should try to keep backwards compatibility. So rather than having ALGO-WAITING, i would suggest using the first available routing algorithm as the default.

So the backwards compatible way would be:

1. Add a hard interface, which automagically creates the soft interface with the first available routing algorithm.

For those who want to play with new routing algorithms:

1. Create the soft interface
2. Change the routing algorithm away from the default
3. Add the first hard interface.

I think that currently point 1) and 3) are joint. So adding something in between means redesign the initialisation part.
