Title:
  cloudinit fails with duplicate mac address on tunnel interfaces

Status in cloud-init:
  Expired

Bug description:
  Cloudinit fails with duplicate mac address while trying to read mac addresses for tunnel interfaces.
  Tunnel interfaces copying mac from main interface, so it will definitely have duplicate macs. 

  
  There are different types of tunnels in linux kernel, based on https://github.com/torvalds/linux/blob/9e9fb7655ed585da8f468e29221f0ba194a5f613/include/uapi/linux/if_arp.h#L67 they have types '768', '769', '776', '777'.

  Should cloudinit skip those interfaces?

  I have a patch for https://github.com/canonical/cloud-
  init/blob/main/cloudinit/net/__init__.py. If it will help.
