So the bluetooth frame arrives and has a type byte first, and then
addresses beyond that?  In that case, it feels to me like the header
length is 0 and it's all data.  Is this the complete on-the-air frame?
Or is this after some parsing?

Are you going to add this to a bluetooth device driver, or is there
some bluetooth code a la net80211 you are thinking of?
