If anyone has any objections, please let me know. ------------------ From: Brian Grech [ Upstream commit 2373107782a98ba15931a37bbd9dd46d7213e5aa ] The commit message for af8c8a450bf4 ("selftests: net: Add FIN_ACK processing order related latency spike test") states: "if the latency is larger than 1 second (spike), print a message". However the code uses a threshold of 100000 us (100 ms), not 1000000 us (1 s). The lower threshold causes false positives on slower hardware where normal connection latency occasionally exceeds 100 ms but never approaches the 1 s spike that indicates the actual FIN/ACK race bug. Fix the threshold to match the documented intent.
