What I was getting at, originally, was that the multi6 layer may have some
information that it can pass up to the ULP, and the ULP then might make
some decisions based upon it.  Additionally, the ULP could potentially
make requests to the multi6 layer, for example, to change the connectivity.

Anyhow, I don't think we can map out this entire space & probably should not.
