I am actively working on this right now. Please see the bms_netdev 
branch in p4 for progress. The code there must be considered pre-alpha, 
it's a development branch.

At the moment I am constructing baseline regression tests to make sure 
that everything works according to spec. It's harder than it looks as 
there are a few places where the delta-based vs the SSM API can lead to 
inconsistency and the specs are not completely unambiguous.
