From 6a94b8ccf6b77f005ab1b36a878e1d81df0c033e Mon Sep 17 00:00:00 2001 From: Michal Kubecek Date: Sun, 26 Jan 2020 23:11:04 +0100 Subject: ethtool: provide message mask with DEBUG_GET request Implement DEBUG_GET request to get debugging settings for a device. At the moment, only message mask corresponding to message level as reported by ETHTOOL_GMSGLVL ioctl request is provided. (It is called message level in ioctl interface but almost all drivers interpret it as a bit mask.) As part of the implementation, provide symbolic names for message mask bits as ETH_SS_MSG_CLASSES string set. Signed-off-by: Michal Kubecek Reviewed-by: Andrew Lunn Signed-off-by: David S.
