It was my understanding that the reason for this was that the first 
implementation for DVR was only done for OVS, probably because it is the 
default. Or is there some reason to assume that DVR also cannot be made 
to work with linuxbridge within Liberty?

FWIW, I think I made some progress in getting [1] to work, though if 
someone could jump in and make a proper patch from my hack, that would 
be great.
