[PATCH 3.12 004/101] gre6: Move the setting of dev->iflink into the ndo_init functions.

[Jiri Slaby]

From: Steffen Klassert <steffen.klassert@xxxxxxxxxxx>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

[ Upstream commit f03eb128e3f4276f46442d14f3b8f864f3775821 ]

Otherwise it gets overwritten by register_netdev().
