Solve the following python programming problem given the following code:
def _link_mac_pxe_configs(task) : 
    'Link each MAC address with the PXE configuration file.

    :param task: A TaskManager instance.

    ' 
    def create_link(mac_path) : 
        ironic_utils.unlink_without_raise (mac_path) 
        relative_source_path = os.path.relpath (pxe_config_file_path, os.path.dirname (mac_path)) 
        utils.create_link_without_raise (relative_source_path, mac_path) 
pxe_config_file_path = get_pxe_config_file_path (task.node.uuid) 
    for mac in driver_utils.get_node_mac_addresses (task) : 
        create_link (_get_pxe_mac_path (mac)) 
        if CONF.pxe.ipxe_enabled : 
            create_link (_get_pxe_mac_path (pxe_config_file_path, delimiter = '')) 

    
    

    Fix the buggy line: create_link (_get_pxe_mac_path (pxe_config_file_path, delimiter = ''))
