Arnd Bergmann 0eb16f82ec ip_tunnel: fix building with NET_IP_TUNNEL=m
When af_mpls is built-in but the tunnel support is a module,
we get a link failure:

net/mpls/af_mpls.o: In function `mpls_init':
af_mpls.c:(.init.text+0xdc): undefined reference to `ip_tunnel_encap_add_ops'

This adds a Kconfig statement to prevent the broken
configuration and force mpls to be a module as well in
this case.

menuconfig MPLS
bool "MultiProtocol Label Switching"
default n
---help---
MultiProtocol Label Switching routes packets through logical
circuits. Originally conceived as a way of routing packets at
hardware speeds (before hardware was capable of routing ipv4 packets),
MPLS remains a simple way of making tunnels.
If you have not heard of MPLS you probably want to say N here.
if MPLS
config NET_MPLS_GSO
tristate "MPLS: GSO support"
help
This is helper module to allow segmentation of non-MPLS GSO packets
that have had MPLS stack entries pushed onto them and thus
become MPLS GSO packets.
config MPLS_ROUTING
tristate "MPLS: routing support"
depends on NET_IP_TUNNEL || NET_IP_TUNNEL=n
---help---
Add support for forwarding of mpls packets.
config MPLS_IPTUNNEL
tristate "MPLS: IP over MPLS tunnel support"
depends on LWTUNNEL && MPLS_ROUTING
---help---
mpls ip tunnel support.
