description:
    - Sends an arbitrary netconf command on HUAWEI CloudEngine switches.
author:
    - wangdezhuang (@QijunPan)
notes:
    - This module requires the netconf system service be enabled on the remote device being managed.
    - Recommended connection is C(netconf).
    - This module also works with C(local) connections for legacy playbooks.
options:
    rpc:
        description:
            - The type of rpc.
        required: true
        choices: ['get', 'edit-config', 'execute-action', 'execute-cli']
