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.

MPLS configuration
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.
