[Babel-users] Babel extension mechanism

[Dave Taht]

One of my thoughts for "flags" originally was to indicate a unicast
ability (which makes more sense than multicast for smaller modern wifi
networks and even more sense with the new RTT metric) in hello and ihu
messages... being able to work over and test the path that most
packets actually take is an advantage...

... but perhaps it could be relegated to a tlv or merely "deduced".
