Test that when the hash policy is set to custom, traffic is distributed only according to the inner fields set in the fib_multipath_hash_fields sysctl. Each time set a different field and make sure traffic is only distributed when the field is changed in the packet stream. The test only verifies the behavior of IPv4/IPv6 overlays on top of an IPv6 underlay network. The previous patch verified the same with an IPv4 underlay network.
