Subject: [PATCH net v2 09/17] selftests: forwarding: hw_stats_l3_gre: Skip when using veth pairs
Date: Tue, 8 Aug 2023 17:14:55 +0300	[thread overview]
Message-ID: <20230808141503.4060661-10-idosch@nvidia.com> (raw)
In-Reply-To: <20230808141503.4060661-1-idosch@nvidia.com>

Layer 3 hardware stats cannot be used when the underlying interfaces are
veth pairs, resulting in failures:

 # ./hw_stats_l3_gre.sh
 TEST: ping gre flat                                                 [ OK ]
 TEST: Test rx packets:                                              [FAIL]
         Traffic not reflected in the counter: 0 -> 0
 TEST: Test tx packets:                                              [FAIL]
         Traffic not reflected in the counter: 0 -> 0

Fix by skipping the test when used with veth pairs.

Fixes: 813f97a26860 ("selftests: forwarding: Add a tunnel-based test for L3 HW stats")
Reported-by: Mirsad Todorovac <mirsad.todorovac@alu.unizg.hr>
Closes: https://lore.kernel.org/netdev/adc5e40d-d040-a65e-eb26-edf47dac5b02@alu.unizg.hr/
