Does the current edge network CNI plugin only support flannel?

@slm940208 Thank you for raising issue. in fact, all of cni network solutions(like flannel, calico) are supported in OpenYurt because no modification has been made to Kubernetes.

but use cni network solution directly in cloud-edge scenario, when network connection between cloud and edge offline, if cni network plugin restart for some reason(like node reboot), the edge network settings maybe can not recover because network plugin can not get metadata(like service, endpoints) from cloud.

@slm940208 and for flannel, we have made some optimization in order to solving the above problems. you can dive into the detail design here: https://openyurt.io/docs/user-manuals/network/edge-pod-network/

@rambohe-ch Thank you for your reply. The current community only gives Flannel's modification scheme？
