NB: DCCP is unicast.

But DCCP does in fact have a mechanism, called Data Dropped, for
differentiating congestion losses from non-congestion losses (such as
receive-buffer or corruption losses).  Non-congestion losses aren't treated
as congestion, as long as we _know_ they weren't due to congestion.
