[Bloat] ECN issues

[Dave Taht]

In my case I just managed to show that congestive (rather than path)
loss can be a factor in the reliability of even a low rate, CS6
prioritized, link local multicast routing protocol (babel), over
present day linux wifi, even using a modern fq+aqm+ecn system.

Enabling ECN markings in babel and watching for CEs while under load, here:

I am not sure where to go with that, but I am deploying it at a small
scale anyway, as gathering link local rtt information somewhat
passively at the moment and point of congestion is important to guide
my other work on wifi. No plans for a paper or presentation, it was
just "interesting", let me know if you have any ideas in addition to
this

as to where to go with it.
