[olsr-dev] Olsr quality extensions metric

[Thomas Lopatic]

Ha! I got it. At least the 1-hop path versus 2-hop path thing. Suppose
that we have two hops, one between node A and node B, another between
node B and node C. Then node A re-sends its packets until it gets an
acknowledgement from B. That's why the ETX for the complete 2-hop path
is not 1 / (total link quality of the 2-hop path), I guess.

The rest is still beyond me, though. :-)
