## Patch Changes

### Patches Added

* **0022-EKS-PATCH-AWS-Include-IPv6-addresses-in-NodeAddresse.patch**
  * This patch is taken from a 
    [commit](https://github.com/anguslees/kubernetes/commit/f8ea814e2d459a900bfb5e6f613dbe521b31515b)
    by GitHub user [anguslees](https://github.com/anguslees). Some of this code was originally in 
    [upstream Kubernetes PR #86918](https://github.com/kubernetes/kubernetes/pull/86918), but it was closed without
    being added to Kubernetes because the PR was not merged before legacy cloud providers new feature freeze, which 
    started in Kubernetes 1.21.
  * The change modifies the in-tree cloud provider code to append ipv6 addresses to the Node object advertised by the
    kubelet.
