## Calico with vxlan encapsulation

Calico hits a kernel bug when using vxlan encapsulation and the checksum offloading of the vxlan interface is on.
The issue is described in the [calico project](https://github.com/projectcalico/calico/issues/3145) and in
[rke2 project](https://github.com/rancher/rke2/issues/1541). The workaround we are applying is disabling the checksum
offloading by default by applying the value `ChecksumOffloadBroken=true` in the [calico helm chart](https://github.com/rancher/rke2-charts/blob/main/charts/rke2-calico/rke2-calico/v3.19.2-203/values.yaml#L51-L53).

This issue has been observed in Ubuntu 18.04, Ubuntu 20.04 and openSUSE Leap 15.3
