From 6fe82a39e583a50f28f03b294df79c9de9ec0de4 Mon Sep 17 00:00:00 2001 From: Veaceslav Falico <vfalico@gmail.com> Date: Thu, 17 Jul 2014 20:33:32 +0200 Subject: net: print a notification on device rename Currently it's done silently (from the kernel part), and thus it might be hard to track the renames from logs. Add a simple netdev_info() to notify the rename, but only in case the previous name was valid. CC: "David S.
