      Description of problem:

      When eBPF flow filter is used, FLP doesn't receive any flows when Kafka is enabled.  When you disable Kafka, everything works as expected.

      Steps to Reproduce:

      1. Create a FlowCollector instance with Loki enabled, Kafka enabled, and sampling = 1.
      
      2. In Observe > Network Traffic, Traffic flows table, Verify that you are seeing traffic on port 53 (or some other port).
      
      3. Configure an eBPF flow filter such as:
        agent:
          ebpf:
            flowFilter:
              enable: true
              action: Accept
              cidr: 0.0.0.0/0
              ports: 53  # change accordingly
              protocol: TCP
      
      4. No traffic appears.

      Actual results:

      A notification appears in Web console saying that FLP hasn't received any flows.

      Expected results:

      Flows in the Traffic flow table with source port 53 or destination port 53
