Tobiko test test_ping_dscp needs to execute tcpdump locally inside the test-pod spawned by the test-operator. As of now the test pod that executes the tobiko tests does not have sufficient privileges to run tcpdump. One possible fix is to add correct securityContext as here:

---
apiVersion: v1
kind: Pod
metadata:
  name: tobiko
spec:
  containers:
  - name: tobiko
    image: quay.io/lpiwowar0/experiment-openstack-tobiko:experiment-42
    command: ["/bin/sh", "-c", "--"]
    args: ["tcpdump -i eth0"]
    securityContext:
      runAsUser: 0
      capabilities:
        add: ["NET_ADMIN", "NET_RAW"] 

DoD:

• We can execute tcpdump from within the tobiko test pod spawned by the test operator.
