Aside from the sampling tests, all others fail due to:
2025-10-17T15:42:47.460Z|00046|netdev_linux|WARN|br-int: creating tap
device failed: Invalid argument
Did you already have OVS running before starting the test suite? And a
br-int configured?
It might be good to cleanup all OVS configuration you have on your test
host and restart the OVS service.
Also, all these tests pass in CI:
https://github.com/ovn-org/ovn/actions/runs/18654250804/job/53239258125
https://github.com/ovn-org/ovn/actions/runs/18654250804/job/53239258245
https://github.com/ovn-org/ovn/actions/runs/18654250804/job/53239258167
Including the ACL sampling ones:
https://github.com/ovn-org/ovn/actions/runs/18654250804/job/53239258245#step:11:4042
Maybe your nfcapd version is old/different?
