From 1c5bf998b3dca0599a2cce885619ffc06fc594df Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sat, 18 Jun 2016 10:45:35 +0200 Subject: [PATCH] ieee802154: allow netns create of lowpan interface This patch reverts commit f9d1ce8f81eb ("ieee802154: fix netns settings"). The lowpan interface need to be created inside the net namespace where the wpan interface is available. The wpan namespace can be changed only by nl802154 before. Without this patch it's not possible to create a lowpan interface for a wpan interface which isn't inside init_net namespace.
