Subject: [PATCH iproute2-next] ip: ipneigh: json: print ndm_flags as boolean attributes

From: Julien Fortin <julien@...ulusnetworks.com>

Today the following attributes are printed as json "null" attributes
NTF_ROUTER
NTF_PROXY
NTF_EXT_LEARNED
NTF_OFFLOADED

$ ip -j neigh show
[
  {
    "dst": "10.0.2.2",
    "dev": "enp0s3",
    "lladdr": "52:54:00:12:35:02",
    "router": null,
    "proxy": null,
    "extern_learn": null,
    "offload": null,
    "state": [
      "REACHABLE"
    ]
  }
]

The goal of this patch is to replace those null attributes with booleans

$ ip -j neigh show
[
  {
    "dst": "10.0.2.2",
    "dev": "enp0s3",
    "lladdr": "52:54:00:12:35:02",
    "router": true,
    "proxy": true,
    "extern_learn": true,
    "offload": true,
    "state": [
      "REACHABLE"
    ]
  }
]
