** Description changed:

  When attempting to verify sru for bug 1669860, I found that vlans
  are not properly filtered out by 'get_interfaces_by_mac'.  That means
  that the bug is still present with vlans.
  
+ The reason for this is that /sys/class/net/<vlan_name>/addr_assign_type
+ shows '0' for a vlan on 4.4, but (correctly) shows '2' on 4.8.
+ See https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-class-net
+ for doc on addr_assign_type.
