Proposed Functionality

Add lib mapper for the device param for ncclient

Use Case

Working with netconf using ncclient, add default mappings.

@jeffkala to provide more clarity.

When using ncclient, you can specify device_parms as

{
        "connection_options": {
            "netconf": {
                "extras": {
                    "hostkey_verify": False,
                    "timeout": 300,
                    "allow_agent": False,
                    "look_for_keys": False,
                    "port": 830,
                    "device_params": {"name": "iosxe"},  #<===
                },
            },
        }
}

Would be good to have cisco_xe' --> iosxe` for the ncclient
