Merge branch 'improve-stability-of-big_tcp_tunnels-sh-selftest' Alice Mikityanska says: ==================== Improve stability of big_tcp_tunnels.sh selftest This series addresses flakiness of big_tcp_tunnels.sh discussed at: https://lore.kernel.org/netdev/349c582c-73e3-468c-91cd-ad6cc3562700@app.fastmail.com/ Lower the thresholds to avoid failures like this (number of packets below the threshold): https://netdev-ctrl.bots.linux.dev/logview.html?f=/logs/vmksft/net-dbg/results/754376/28-big-tcp-tunnels-sh/stdout Tweak tcp_min_tso_segs and initcwnd to avoid failures like this (BIG TCP doesn't kick in in slow configurations): https://netdev-ctrl.bots.linux.dev/logview.html?f=/logs/vmksft/net-dbg/results/751124/21-big-tcp-tunnels-sh/stdout v2 changes: Use $KSFT_MACHINE_SLOW instead of probing kernel config. v1: https://lore.kernel.org/netdev/20260814194124.3102581-1-alice.kernel@fastmail.im/ ==================== Link: https://patch.msgid.link/20260822120308.1165200-1-alice.kernel@fastmail.im Signed-off-by: Jakub Kicinski <kuba@kernel.org>
