Error unmarshaling enums

[Kamil]

Currently enums are not unmarshaled correctly in example in bgp-request(address_families):

{
    "bgp-router": {
        "parent_type": "routing-instance",
        "fq_name": [
            "default-domain",
            "default-project",
            "ip-fabric",
            "__default__",
            "pawel.marchewka.novalocal"
        ],
        "uuid": null,
        "bgp_router_parameters": {
            "vendor": "contrail",
            "admin_down": false,
            "router_type": "control-node",
            "ipv6_gateway_address": null,
            "local_autonomous_system": null,
            "auth_data": null,
            "autonomous_system": 64512,
            "cluster_id": null,
            "address": "192.168.0.14",
            "source_port": null,
            "gateway_address": null,
            "identifier": "192.168.0.14",
            "hold_time": 0,
            "port": "179",
            "address_families": {
                "family": [
                    "route-target",
                    "inet-vpn",
                    "e-vpn",
                    "erm-vpn",
                    "inet6-vpn"
                ]
            }
        }
    }
}
