      Previously, network flows were not generated in OpenShift 4.15, with the eBPF agents showing errors "could not attach TCX hook" in logs. Users had to configure a workaround by adding in Flowcollector, under spec.agent.ebpf.advanced.env, "TC_ATTACH_MODE: tc".
      This configuration is not needed any more: it is now done automatically when the detected cluster version is 4.15.

      Flows are not observed on OCP4.15. Issue seen with Source, y-stream and redhat-operators catalogs

      Slack convo: thread

      WORKAROUND:
      In FlowCollector spec.agent.ebpf.advanced.env set TC_ATTACH_MODE to tc
