DataSource description documentation

Describe
The documentation regarding Datasources is not 100% clear regarding the field desc_id :

• The field “desc_id” represent the device type, I understood it can be 13, 3 or '254' for a client but the docs is unclear on the meaning of this. Here is the mapping:

{"1": "Zone",
"2": "ERC",
 "3": "Datasource",
"4": "Database Event Monitor (DBM)",
"5": "DBM Database",
 "7": "Policy Auditor",
"10": "Application Data Monitor (ADM)",
 "12": "ELM",
"14": "Local ESM",
"15": "Advanced Correlation Engine (ACE)",
"16": "Asset datasource",
 "17": "Score-based Correlation",
"19": "McAfee ePolicy Orchestrator (ePO)",
"20": "EPO",
"21": "McAfee Network Security Manager (NSM)",
"22": "McAfee Network Security Platform (NSP)",
 "23": "NSP Port",
 "24": "McAfee Vulnerability Manager (MVM)",
"25": "Enterprise Log Search (ELS)",
"254": "Client group",
 "256": "Client"}

We should rehabilitate the method _insert_desc_names (which is commented) in DevTree to insert the datasource type as String in a new DataSource field : desc
