[PATCH 0/2] DCCP: Improve loss interval handling some more

[Ian McDonald]

Folks,

At present we don't track if we lose a burst of packets in a row which means
we get a series of loss intervals with length 1. What this means is that
performance suddenly slumps. Not good. This fix made a big difference for
me - increased performance from 10 Kbits to 200 Kbits on a constrained
1 Mbits link (and then I fixed to higher again later - see my blog).

I've got a fix here for this in a basic form. It doesn't address the
requirement that they be within the same RTT (measured by CCVal) but is
still better than what we have.

I realise that this is slightly different to how Gerrit is tackling as he is
adding CCVal support and looking at using array. Consider this a "March"
patch unless you want to look at sooner. If nothing else it might give ideas
for people on how to do it even better.
