This issue is common when a connection has extended periods of one packet chit-chat beyond the min RTT filter window. The first patch does that for TCP general min RTT estimation. The second patch addresses specifically the BBR congestion control's min RTT filter. ==================== Signed-off-by: David S. Miller --- 3c1693f012bdc0a9ff1bf030f7abc9961e94211f
