Always

1. Label one worker node as egress node and enable ipforarding on it
2. Create an egressip object, it can be assigned to egress node
oc get egressip
NAME         EGRESSIPS      ASSIGNED NODE                         ASSIGNED EGRESSIPS
egressip-1   172.22.0.100   worker-2.sriov.openshift-qe.sdn.com   172.22.0.100

oc get egressip -o yaml

3. Create a namespace test and some pods on it. add a label to namespace matching egressIP object.
4. From pod to access the bastion host

Outgoing traffic was timeout

From bastion node,it didn't get correct MAC for egressIP
? (172.22.0.100) at <incomplete> on sriovpr

egressIP was not added to secondary NIC on egress node

EgressIP works well on secondary NIC
