Pattan, Reshma Oct. 21, 2015, 10:50 a.m. UTC
The reorder library unit test was performed under the assumption that the start
sequence number was always 0.
This is not the case anymore as the start sequence number is initialized by the first
packet inserted into the reorder buffer.

This patch updates the unit test to reflect the new behavior.

Fixes: 7e1fa1de8a53 ("reorder: allow random number as starting point")

Version 2:
split patch for unit test only
