Using Calico networking with VXLAN encapsulation results in packet loss

Issue

• Using Calico networking with VXLAN encapsulation results in packet loss
• As per RKE2 documentation https://docs.rke2.io/known_issues/#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 and in rke2 project. The workaround we are applying is disabling the checksum offloading by default by applying the value ChecksumOffloadBroken=true in the calico helm chart.
