Collaboration diagram for Nearer term TODOs:

Todo:: Think about how to implement packet injection so we can test without a network...

Only need to do it for the LLDP/PCAP layer and the UDP layer. For UDP also need to dummy up transmitting packets...

Todo:: Decide how to structure/document system differences for portability

Todo:: Write code to encapsulate libpcap packets along with the header info etc - similar to what would be needed to create a pcap file from it / or maybe the exact pcap file format image?

Todo:: What should we do about logging? - glib logging?

Carefully check the heartbeat IPC GSource code to make sure we understand how to respond to back-pressure and resume transmitting after the flow control is removed.
