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.

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.

that have had MPLS stack entries pushed onto them and thus

become MPLS GSO packets.
