Before this CL, a SACK was generated from scratch based on information about each received fragment, to generate correct gap-ack-blocks. When there was a lot of data in the data tracker (due to packet loss), this took considerate time, as generating a SACK was O(N), where N is the amount of fragments in the data tracker. By instead having precomputed gap-ack-blocks that are continuously updated, generating a SACK is much faster and the memory usage goes down a bit as well.
