In my recent testing on RPI, I have found the following problems:
1) some strange core dumps with debugging unless I set -O0.
2) DIS messages, and perhaps all unicast messages, are not being sent.
I have code not yet pushed up yet.
I have neither confirmed nor denied that this occurs with VMs.

You saw unicase DIS messages going out? I did not.
I am hoping to be able to spend more time on this starting Sunday.
