If anyone has any objections, please let me know. ------------------ From: Steffen Klassert [ 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(). Signed-off-by: Steffen Klassert Signed-off-by: David S.
