af-packet config from suricata.yaml:

    - interface: ens5f0
      cluster-id: 99
      cluster-type: cluster_flow
      defrag: yes
      rollover: yes
      use-mmap: yes
      mmap-locked: yes
      ring-size: 4096
      buffer-size: 65536

Attached is the startup script I'm using, slighly modified version
of one Coop sent me.

Thanks for your help.
