[ovs-dev] [PATCH] ovn.at: fix occasional failure - ACL reject rule test

[Han Zhou]

The test fails occasionally because it may starts sending packets
before the new ACL related flows are installed on HVs, even if it
ensures lflows exist in SB DB. This patch ensure the HVs are in
sync by ovn-nbctl --wait=hv sync, and removes the check for lflow
readiness in SB.
