Delete address example

[joseph-henry]

Hello. Nice little library you have here. I'm still a rust novice and while I was able to add addresses to a link I cannot figure out how to remove an address and there is no example showing this process.

The closest thing I can come up with is:

  pub async fn del_addr(link_name: &str, ip: IpNetwork) -> Result<(), Error> {
      let (connection, handle, _) = new_connection().unwrap();
      tokio::spawn(connection);

      let mut links = handle.link().get().match_name(link_name.to_string()).execute();

      let mut req = handle.address().get().set_address_filter(ip.ip());
      let mut msg = req.message_mut();

      if let Some(link) = links.try_next().await? {
          if let Err(e) = handle.address().del(msg.clone()).execute().await
          {
              eprintln!("{e}");
          }
      }
      Ok(())
  }

This results in Error 95 "Operation Not Supported"

Can somebody point me in the right direction? Thanks.
