From 4c349b628e3e9c651e7c2e35c36e22d043825b1d Mon Sep 17 00:00:00 2001 From: Lukasz Czapnik Date: Fri, 8 Feb 2019 12:50:42 -0800 Subject: [PATCH] ice: Fix for FC get rx/tx pause params Ethtool reported pause params based on the currently negotiated link settings instead of current PHY config. User was not able to turn off pause params because ethtool was incorrectly reporting parameters as off when link was down even though PHY was configured to support pause frames. Now pause params are taken from PHY config instead of link status.
