From 310145642312e1c5fb3d8efa8321cf905d0354c4 Mon Sep 17 00:00:00 2001 From: Krzysztof Galazka Date: Fri, 12 Jun 2026 13:56:15 +0200 Subject: [PATCH] ice(4): Fix link speed after changing cable type When interface was connected to a link partner with a cable type limitting maximum supported speed, e.g. SFP+ cable in 25G port, driver incorrectly saved a supported speed as the user configured speed. This prevented interface from using all supported speeds after switching cable to SFP28. Link was established at 10G as supported by previously used SFP+ cable. Don't set user requested speed unless actually configured by an user, to allow automatic selection of highest available speed. Only when user sets custom config using advertise_speed sysctl save it and try to apply after cable is changed. Also don't save initial supported speeds if FW supports reporting default PHY config.
