From a1c234f95cae2d293047bb6c36e7a4840dbac815 Mon Sep 17 00:00:00 2001 From: Jiri Benc Date: Fri, 14 Aug 2015 16:40:40 +0200 Subject: lwtunnel: rename ip lwtunnel attributes We already have IFLA_IPTUN_ netlink attributes. The IP_TUN_ attributes look very similar, yet they serve very different purpose. This is confusing for anyone trying to implement a user space tool supporting lwt. As the IP_TUN_ attributes are used only for the lightweight tunnels, prefix them with LWTUNNEL_IP_ instead to make their purpose clear. Also, it's more logical to have them in lwtunnel.h together with the encap enum.
