[PATCH 3.14 003/122] vti6: Use vti6_dev_init as the ndo_init function.

[Greg Kroah-Hartman]

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

------------------

From: Steffen Klassert <steffen.klassert@xxxxxxxxxxx>

[ Upstream commit 16a0231bf7dc3fb37e9b1f1cb1a277dc220b5c5e ]

vti6_dev_init() sets the dev->iflink via a call to
vti6_link_config(). After that, register_netdevice()
sets dev->iflink = -1. So we loose the iflink configuration
for vti6 tunnels. Fix this by using vti6_dev_init() as the
ndo_init function. Then vti6_dev_init() is called after
dev->iflink is set to -1 from register_netdevice().
