From 4eed4b87f17d10b7586349c13c3a30f9c24c9ba4 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 8 May 2024 23:21:17 +0200 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.
