        Description
            Based on either the vport name or the physical port, get the Topology
            Group object and all the protocols in each Device Group within the same 
            Topology Group.

        Parameter
            port: [chassisIp, cardNumber, portNumber]
                  Example: ['10.10.10.1', '2', '8']

            portName: <str>: The virtual port name.

        Example usage:
            protocolObj = Protocol(mainObj)
            protocolList = protocolObj.getProtocolListByPortNgpf(port=['192.168.70.120', '1', '2'])

            Subsequently, you could call getProtocolObjFromProtocolList to get any protocol object handle:
            obj = protocolObj.getProtocolObjFromProtocolList(protocolList['deviceGroup'], 'bgpIpv4Peer')
