dccp: generalise data-loss condition ...
This patch generalises the task of determining data loss from RFC 4340, 7.7.1.
Let S_A, S_B be sequence numbers such that S_B is "after" S_A, and let
N_B be the NDP count of packet S_B. Then, using modulo-2^48 arithmetic,
D = S_B - S_A - 1 is an upper bound of the number of lost data packets,
D - N_B is an approximation of the number of lost data packets
(there are cases where this is not exact).
The patch implements this as
dccp_loss_count(S_A, S_B, N_B) := max(S_B - S_A - 1 - N_B, 0)
