I have read that we only need a special software(driver) in order to support WiFi Direct in a specific operating system, that is to say, we don't need buying new network interfaces, so the key is the software.
Assuming that it's true, I want to know What are the operating systems that have support for WiFi Direct? I know that Android has support, but I want to know about others operating systems
Like a open source enthusiastic, I would like reading that Linux has support for Wifi Direct, but doesn't matter if Windows has support :D
