      Description of problem:

      Created this Jira issue to track inter-cluster datapath failures on Baremetal clusters,
      due to bug in UDP checksum calculation by HW.
      Like  [1] for example. 
       
       
      Disabling HW offload  [2] of the vxlan interface created by Submariner resolves the issue.
