Summary

rS330675 (D14540) introduced an extra window check in the LRO code to ensure it captured and reported the highest window advertisement with the same SEQ/ACK. However, the window comparison uses a two's complement comparison rather than a comparison of the absolute values. Because windows use absolute values, rather than two's complement arithmetic (i.e. they don't wrap), compare the absolute values.
