//! Updates a floating IP and its association with an internal port.
//!
//! The association process is the same as the process for the create floating

//!
//! To disassociate a floating IP from a port, set the `port_id` attribute to
//! null or omit it from the request body.
//!
//! This example updates a floating IP:
//!
//! Depending on the request body that you submit, this request associates a

//! Normal response codes: 200
