OK, then we'd better put a big WARNING in the change log/release notes
Because this will break a lot of applications.

I still have a question, according to

SO_BROADCAST is only for sending broadcast messages, not for filtering 
broadcast packets on reception.
Or is there another doc describing this behavior ?

You can also encounter your problem if someone is sending unicast messages to 
your device...
