      7# Test for mirroring to gretap and ip6gretap, such that the neighbor entry for
      8# the tunnel remote address has invalid address at the time that the mirroring
      9# is set up. Later on, the neighbor is deleted and it is expected to be
     10# reinitialized using the usual ARP process, and the mirroring offload updated.
