multi ip pod does not work with aws and calico

[georambo]

K8s version: EKS 1.17.7
cni-genie: release 1.8

Pod Annotations: cni: calico,aws

Whichever cni gets put second, it fails setting up cni, and pod does not get started. I'm not aware of any other way to get communication working between pods on the aws-cni, and pods on the calico-cni. Traffic works fine from calico-cni to aws-cni.
