Title:
  net veth selftest failure

Status in ubuntu-kernel-tests:
  New
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  This is an old error that doesn't seem to happen if we run this test
  isolated from the others, maybe the reason is that something is not
  cleaned up properly (we should probably consider to exclude this test
  from the net tests and run it isolated as a separate test):
