Notes
-----
According to the illustration of the DATA chunks just above it, with "still missing" TSN 13 and TSN 16, the block #2 end=6 not 5.
 --VERIFIER NOTES-- 
Reasoning provided by M. Tüxen: "I think the RFC is correct. The first block is TSN 14 and TSN 15. Since the cumulative TSN ack is 12, this
is [2, 3]. The second block consists only of TSN 17. Therefore is is reported as [5, 5].
The block [5, 6] as you suggest would mean that TSN 17 and TSN 18 would have been received, which
is not the case described in the illustration."
