# MPLS configuration
bool "MultiProtocol Label Switching"
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.
tristate "MPLS: GSO support"
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.
tristate "MPLS: routing support"
depends on NET_IP_TUNNEL || NET_IP_TUNNEL=n
Add support for forwarding of mpls packets.
tristate "MPLS: IP over MPLS tunnel support"
depends on LWTUNNEL && MPLS_ROUTING
mpls ip tunnel support.
