[spp] [PATCH 0/5] Change primary status command to be detailed

[ogawa.yasufumi@lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

Status command of primary simply returns 'running' or 'idling'. It is no
meaning because primary is always running and does not have status
'idling'. It would be helpful for users if status command returns stats
of port forwarding info instead of running status.

This series of patches is for changing status command to show the stats.

  spp > pri;status
  Physical Ports:
    ID          rx          tx     tx_drop  mac_addr
     0    78932932    78932931           1  56:48:4f:53:54:00
  Ring Ports:
    ID          rx          tx     rx_drop     rx_drop
     0       89283       89283           0           0
     ...

For this update, the message format from primary to controller is
changed to be structured as JSON. Socket buffer length is also changed
to 2048 because it might exceed 1000 if network configuration is
complexed. Here is an example of the message format from primary.

  {
      "phy_ports": [
      {
          "eth":
              "56:48:4f:12:34:00",
              "id":
                  0,
              "rx":
                  78932932,
              "tx":
                  78932931,
              "tx_drop":
                  1,
      }
      ...
      ],
      "ring_ports":
          [
          {
              "id":
                  0,
              "rx":
                  89283,
              "rx_drop":
                  0,
              "tx":
                  89283,
              "tx_drop":
                  0
          },
      ...
          ]
  }
