From c19be735c99e221e00157c6db475fe007c056638 Mon Sep 17 00:00:00 2001 From: Flavio Leitner Date: Fri, 5 Dec 2014 22:13:24 -0200 Subject: [PATCH] dummy: add support for ethtool get_drvinfo The command 'ethtool -i' is useful to find details about the interface like the device driver being used. This was missing for dummy driver. Signed-off-by: Flavio Leitner Signed-off-by: David S.
