Your problem seems to be similar to mine (I also see received packets on the interface), however I haven't been able to reproduce it on any of several 4.9 and 4.10 machines I tested it on (on the other hand my test program works every time on 5.3). It may be a subtle timing issue. I got a private reply from Tony Ackerman, he is looking into this. -- Pierre Beyssac pb@enst.fr
