From a54acb3a6f853e8394c4cb7b6a4d93c88f13eefd Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Thu, 2 Apr 2015 17:07:00 +0200 Subject: dev: introduce dev_get_iflink() The goal of this patch is to prepare the removal of the iflink field. It introduces a new ndo function, which will be implemented by virtual interfaces. There is no functional change into this patch. All readers of iflink field now call dev_get_iflink().
