Detailed Description

Unit test for the TCP Forward Acknowledgment (FACK) implementation.

This unit test creates a short packet flow and forces four consecutive lost segments, and verifies that the snd.fack variable is updated to the highest sequence number present in the incoming SACK blocks, and that its external calculation of awnd matches the internal state variable.
