From 0d042007945d6fadb9b59ce8d01502575689067d Mon Sep 17 00:00:00 2001 From: Michal Kubecek Date: Sun, 23 Aug 2020 21:40:42 +0200 Subject: [PATCH 11/17] build: add -Wextra to default CFLAGS As a result of previous commits, ethtool source now builds with gcc versions 7-11 without any compiler warning with "-Wall -Wextra". Add "-Wextra" to default cflags to make sure that any new warnings are caught as early as possible.
