That's correct.  cgc is the data from the packet command that was sent
in from the ioctl.  The user application is actually the one that
decides whether you get to see the message or not.  Modern apps like hal
set it because they take care of all state updates and notifications
themselves.  Which is the application that's doing this (because it
probably needs updating).
