Yeah, this reproduces easily on my laptop. The switches are somehow much more quiet and do not really hit the issue. Mirsad, can you please try this patch? It fixes the issue for me. >From 77461c209eb0067dca7fdf4431a907b2a1ce8c6a Mon Sep 17 00:00:00 2001 Message-ID: <77461c209eb0067dca7fdf4431a907b2a1ce8c6a.1690887929.git.petrm@nvidia.com> From: Petr Machata Date: Tue, 1 Aug 2023 12:57:53 +0200 Subject: [PATCH net-next] selftests: mirror_gre_changes: Tighten up the TTL test match To: This test verifies whether the encapsulated packets have the correct configured TTL. It does so by sending ICMP packets through the test topology and mirroring them to a gretap netdevice. On a busy host however, more than just the test ICMP packets may end up flowing through the topology, get mirrored, and counted. This leads to potential spurious failures as the test observes much more mirrored packets than the sent test packets, and assumes a bug. Fix this by tightening up the mirror action match. Change it from matchall to a flower classifier matching on ICMP packets specifically.
