Hmm so I think what I'll do is this...

 both: ndm_flags = 0 
 sw  : ndm_flags = NTF_SW_FDB
 hw  : ndm_flags = NTF_HW_FDB

Then current tools will work with embedded bridges and software
bridges
with the interesting case being when a port supporting an offloaded
FDB is attached to a SW bridge. Doing both in this case seems to be a
reasonable default to me.

Looks good, although it seems like no backward compat is broken, it
feels like the default should be whats goin on today i.e s/ware only.
IOW, I would make that the 0.
