From f43960dac3f0c50683d3fa1d25d0b75335212ed2 Mon Sep 17 00:00:00 2001 From: Danielle Ratson Date: Tue, 2 Feb 2021 20:06:07 +0200 Subject: [PATCH] ethtool: Get link mode in use instead of speed and duplex parameters Currently, when user space queries the link's parameters, as speed and duplex, each parameter is passed from the driver to ethtool. Instead, get the link mode bit in use, and derive each of the parameters from it in ethtool.
