I'm seriously thinking about changing the phylink_validate() interface such that the question of which link _modes_ are supported no longer comes up with MAC drivers, but instead MAC drivers say what interface modes, speeds for each interface mode, duplexes for each speed are supported.BTW this would also solve the situation where DSA needs to know which interface modes are supported on a particular port to know which modes we can try on SFP connected to a DSA port.What do you mean here? What makes this specific to DSA?
