From 14b19c7d407793b4d40f459dc366e3471a5c007c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Sat, 2 Jan 2016 22:15:31 +0000 Subject: ledtrig-netdev: add support for renamed devices The ppp0 interface is renamed after the connection is established. Due to a missing NETDEV_REGISTER event, the ledtrig-netdev isn't aware of the renamed interface and literally ignores the device (no tx/rx indication, led isn't switched off with 'ifdown wan').
