+Subject: [PATCH 5/5] net: ethernet: cortina: Implement .set_pauseparam()
+
+The Cortina Gemini ethernet can very well set up TX or RX
+pausing, so add this functionality to the driver in a
+.set_pauseparam() callback. Essentially just call down to
+phylib and let phylib deal with this, .adjust_link()
+will respect the setting from phylib.
