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