ethtool: add and use message type for tunnel info reply 2020-09-17T23:43:20+00:00 Michal Kubecek mkubecek@suse.cz 2020-09-16T23:04:10+00:00 19a83d36f9837e8bd27435ebb31564a717a5d15a Tunnel offload info code uses ETHTOOL_MSG_TUNNEL_INFO_GET message type (cmd field in genetlink header) for replies to tunnel info netlink request, i.e. the same value as the request have.

For example, vendor can expose 'Autoneg' as link_ext_state and add 'No partner detected during force mode' as link_ext_substate.
