Petr, please take a look. Probably need to make the filters more specific. The failure is:
# TEST: mirror to gretap: TTL change (skip_hw) [FAIL] # Expected to capture 10 packets, got 14.
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.

Message-ID: 77461c209eb0067dca7fdf4431a907b2a1ce8c6a.1690887929.git.petrm@nvidia.com From: Petr Machata petrm@nvidia.com Date: Tue, 1 Aug 2023 12:57:53 +0200 Subject: [PATCH net-next] selftests: mirror_gre_changes: Tighten up the TTL test match To: netdev@vger.kernel.org
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.

The problem seems to be fixed in the test run:
