Uh, which python parser?

The reporter tested the patch, there's a small error. Before is above,
after is:

{
    "kind": "mqprio",
    "handle": "8001:",
    "root": true,
    "options": {
        "tc": 2,
        "map": [ 0,0,0,1,0,1,0,0,0,0,0,0,0,0,0,0 ],
        "queues": [
            "": [ 0,3 ],
            "": [ 4,7 ] ],
        "mode": "channel",
        "shaper": "dcb"
    }
}

Will fix the "queues" to remove the empty name in v2.
