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.
