Steps to Reproduce:

Following the issue #1902 I am opening a new issue as RKE 1.3.3 does not support yet DualStack with Canal. The following error is displayed when deploying a k8s cluster with the above configuration:

level=fatal msg="Failed to validate cluster: Network plugin [canal] does not support IPv6 (dualstack)

Results:

Could you add the support for DualStack with Canal?

It looks like Calico release 3.22.0 contains the fix for Canal deployment with Dual Stack. Any update on RKE side when it will be integrated?
