commit 9a711cde07c245a163d95eee5b42ed1871e73236 upstream.
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")
