Originally defined for the switchdev model, learning_sync is now used
to create a Linux bridge that provides a network interface that merges two
very different fabrics.

In this talk you will learn
- About the motivation for our usecase.
- How we converged a vanilla network segment with a high performance fabric,
that connects only subsets of the segment.
- Why we chose the Linux bridge to do so.
- How we used device-to-bridge and bridge-to-device learning and
how little we had to extend our device driver to do so.
- What remains to be done.
