From 3d2b847fb99cf2b28aa046e486636e555bc6ed1c Mon Sep 17 00:00:00 2001 From: Michal Kubecek Date: Fri, 27 Dec 2019 15:56:23 +0100 Subject: ethtool: provide link state with LINKSTATE_GET request Implement LINKSTATE_GET netlink request to get link state information. At the moment, only link up flag as provided by ETHTOOL_GLINK ioctl command is returned. LINKSTATE_GET request can be used with NLM_F_DUMP (without device identification) to request the information for all devices in current network namespace providing the data.
