# Macro to exclude tests that will fail with TC offload enabled.
+# We currently have the below tests disabled in system-traffic.at
+# for the following reasons:
+#
+# TC does not support moving ports to a different namespace than vswitchd's
+# namespace, so we need to disable this test.
+# - 'conntrack - multiple namespaces, internal ports'
+#
+# The kernel's tcf_ct_act() function does not seem to take care of any (QinQ)
+# VLAN headers causing commits to fail. However, if this is solved, we have to
+# make sure conntrack does not break the VLAN boundary, i.e., putting together
+# two packets with different CVLAN+SVLAN values.
+# - 'conntrack - IPv4 fragmentation + cvlan'
+#
+# Fragmentation handling in ct zone 9 does not seem to work correctly.
+# When moving this test over to the default zone all works fine.
+# - 'conntrack - Fragmentation over vxlan'
+#
+# Occasionally we fail with invalid byte counts.

I commented the three remaining failures when running tc with the system-traffic tests. In addition I ran the following test to verify we did not see any failures with recheck enabled: for i in {1..50}; do make check-offloads || \ make check-offloads TESTSUITEFLAGS="--recheck" || break; \ echo "ALL_50_OK: $i"; done; Unfortunately, a bunch of test cases showed occasional failures. For now, they are excluded from the test cases and need further investigation. They are: datapath - truncate and output to gre tunnel datapath - truncate and output to gre tunnel by simulated packets These tests where executed on a Fedora37 machine with the kernel 6.1.5-200.fc37.x86_64 installed.
