///
/// The following order applies:
///
/// 1. Destination port.
/// 1. Destination IP address.
/// 1. Server name (e.g. SNI for TLS protocol),
/// 1. Transport protocol.
/// 1. Application protocols (e.g. ALPN for TLS protocol).

///    when using a listener filter that overrides the source address, such as the :ref:`Proxy Protocol listener filter <config_listener_filters_proxy_protocol>`).
/// 1. Source type (e.g. any, local or external network).
/// 1. Source IP address.
/// 1. Source port.
///
/// For criteria that allow ranges or wildcards, the most specific value in any
/// of the configured filter chains that matches the incoming connection is going
/// to be used (e.g. for SNI `www.example.com` the most specific match would be
/// `www.example.com`, then `*.example.com`, then `*.com`, then any filter
/// chain without `server_names` requirements).
///
/// A different way to reason about the filter chain matches:
/// Suppose there exists N filter chains. Prune the filter chain set using the above 8 steps.
/// In each step, filter chains which most specifically matches the attributes continue to the next step.
/// The listener guarantees at most 1 filter chain is left after all of the steps.
///
/// Example:
///
/// For destination port, filter chains specifying the destination port of incoming traffic are the
/// most specific match. If none of the filter chains specifies the exact destination port, the filter
/// chains which do not specify ports are the most specific match. Filter chains specifying the
/// wrong port can never be the most specific match.
