This patch supports dump of ring information by its name.
An example using this command is shown below:
--> /ring/info,MP_mb_pool_0
{
"/ring/info": {
"name": "MP_mb_pool_0",
"socket": 0,
"flags": "0x0",
"producer_type": "MP",
"consumer_type": "MC",
"size": 262144,
"mask": "0x3ffff",
"capacity": 262143,
"used_count": 153197,
"mz_name": "RG_MP_mb_pool_0",
"mz_len": 2097536,
"mz_hugepage_sz": 1073741824,
"mz_socket_id": 0,
"mz_flags": "0x0"
}
}
