From aca8bd83117e177f2beac6b9434d36d446a7de64 Mon Sep 17 00:00:00 2001 From: Pavel Moravec Date: Mon, 18 Jan 2021 22:45:43 +0100 Subject: [PATCH] [networking] Collect 'ethtool -e ' conditionally only EEPROM dump collection might hang on specific types of devices, or negatively impact the system otherwise. As a safe option, sos report should collect the command when explicitly asked via a plugopt only.
