Follow-up Comment #13, patch #9384 (project lwip):

> However, the idea of somehow combining the ooseq list with the SACK list
does make sense! Maybe we could think more about it in that direction.

One solution could be to calculate SACKs dynamically by examining the ooseq
list.
To do that, we would need to store some time data (or a value of a counter
stored somewhere
and incremented every time we get a TCP packet) in each TCP segment (to
determine the order of SACKs),
and traverse the entire ooseq list before sending each packet.
