Manual test in DUT

Before change:

admin@str-msn2700a1-03:~$ sonic-cfggen -M /etc/sonic/device_desc.xml --print-data 
{
    "DEVICE_METADATA": {
        "localhost": {
            "hostname": "CPQ21-0101-0509-04T0",
            "hwsku": "Arista-7260CX3-D108C8"
        }
    },
    "LOOPBACK_INTERFACE": {
        "lo_v6|2603:10d0:e:5eb::/128": {}         <==== missing standalone entry which fail YANG
    },
    "MGMT_INTERFACE": {
        "eth0|100.84.101.139/26": {
            "gwaddr": "100.84.101.129"
        },
        "eth0|2603:10e2:f0:7478::b/64": {
            "gwaddr": "2603:10e2:f0:7478::1"
        }
    }
}
