Description Douglas Smith 2021-03-30 13:35:05 UTC 
+++ This bug was initially created as a clone of Bug #1944678 +++

Description of problem: Whereabouts will assign the same IP address to multiple pods.


How reproducible: Always.


Steps to Reproduce:

Create net-attach-def as so:

```
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
  name: macvlan-conf
  annotations:
    k8s.v1.cni.cncf.io/resourceName: mellanox.com/mlnx_sriov_netdevice
spec:
  config: '{
  "type": "macvlan",
  "master": "change_to_ifname_on_your_hosts",
  "cniVersion": "0.3.1",
  "name": "macvlan-network",
  "ipam": {
    "type": "whereabouts",
    "range": "10.199.199.0/24",
    "range_start": "10.199.199.100"
  }
}'
```

Actual results: Duplicate IP address assigned 


Expected results: Unique IP address assigned to each pod.
