Description

Enable the IP address family of the client connection to control the IP address family of the server connection. Currently it can only be set globally to always prefer IPv4 or IPv6. This should be changed to preserve those options and add the ability to prefer the same family as the client connection. This should be configurably globally and be able to be overridden by port configuration and the plugin API.
